Case Study: How Vanda's Kitchen Handles Allergen Compliance

Vanda's Kitchen is a London-based artisan food business supplying premium prepared food and catering services to corporate clients, luxury retailers including Selfridges, and direct-to-consumer through their online store. With a product range spanning dozens of SKUs — many of them featuring complex, multi-ingredient recipes — allergen compliance is central to how the business operates.

This case study explores the allergen challenges Vanda's Kitchen faces, the systems they have built, and the lessons other food businesses can draw from their approach.

The Allergen Challenge at Scale

Vanda's Kitchen's product range includes everything from salads and hot dishes to baked goods, condiments, and festive hamper items. Many products involve bought-in ingredients — stocks, pastes, sauces, spice blends — that themselves contain sub-ingredients which must be assessed for allergens.

Their customer base is diverse in its dietary requirements. Corporate clients ordering for office events may have employees with any of the 14 major allergens. Selfridges customers include people with complex allergy profiles who read labels closely and rely on declared information to make safe purchasing decisions. Direct-to-consumer customers ordering online for themselves or as gifts need accurate information before they purchase.

The consequence of an allergen error — undeclared allergen, incorrect label, cross-contact incident — is not abstract. It is a real customer harmed, a real legal liability, and a real reputational crisis.

Building the Foundation: Recipe Documentation

Vanda's Kitchen's first step was comprehensive recipe documentation. Every product has a detailed recipe card listing every ingredient in full, with the source of each ingredient recorded. For each bought-in ingredient, the business holds a current supplier allergen declaration — and has a process for requesting updated declarations whenever a supplier makes a formulation change.

This documentation is not kept in a static spreadsheet. It is maintained in a centralised system that flags when supplier declarations are approaching their review date and highlights any products affected by a supplier change.

Allergen Matrix: From Kitchen to Customer

The business publishes a comprehensive allergen matrix on its website and provides updated copies to all wholesale accounts. The matrix covers the full product range and all 14 major allergens, clearly distinguishing between "contains" and "may contain" for each product and allergen combination.

For the online store, allergen information appears on every product page — not just on a separate allergen page that customers might not find. Customers can see allergen status before they add a product to their basket, and allergen information is reiterated in the order confirmation email and on the delivery documentation.

Allergen Matrix, the SaltAI Shopify app, powers the product-page and matrix display on Vanda's Kitchen's Shopify store, pulling from their centralised allergen data and keeping the customer-facing information accurate and current.

Handling Corporate Allergen Requirements

For corporate catering orders, Vanda's Kitchen operates a structured pre-order allergen process. When a new corporate client enquires, allergen requirements are captured as part of the briefing. The operations team confirms which products are suitable for which dietary profiles, flags any cross-contact risks, and recommends menu configurations that meet the client's requirements.

Every corporate delivery includes a delivery manifest listing every item and its allergen information. For orders with specific allergen-sensitive requirements, those items are packaged and labelled separately with clear allergy advisory markings.

When a corporate client requests a custom menu — as is common for events and regular office catering — a dedicated allergen review is conducted for every dish before it is added to the order.

Kitchen Controls and Cross-Contact Management

Vanda's Kitchen operates from a kitchen that uses a range of allergens across its product range. Their approach to cross-contact management:

Allergen-sensitive production scheduled first. Products intended for allergy-sensitive customers are produced at the start of a production run, before allergen-containing products are brought out
Dedicated equipment for highest-risk items. Boards, utensils, and small equipment used for products going to customers with severe allergies are dedicated and stored separately
Documented cleaning procedures. Cleaning between allergen-containing and allergen-free production runs is documented and validated
Ingredient storage segregation. Allergen-containing ingredients are stored separately from ingredients used in allergen-free preparations

The business uses a precautionary "may contain" statement on products where a genuine cross-contact risk exists after all controls have been applied, and does not use blanket "may contain" disclaimers.

Staff Training and Culture

Every member of the kitchen team at Vanda's Kitchen completes allergen awareness training as part of their induction. Training covers the 14 major allergens, the consequences of allergic reactions, the business's specific allergen management procedures, and what to do if an allergen risk is identified.

The kitchen team is empowered to stop production if they identify an allergen risk — even mid-run — without fear of criticism. This culture of allergen safety over production efficiency is explicitly supported by management.

Customer service staff are trained to handle allergen enquiries confidently, know which products are suitable for which dietary requirements, and know when to escalate a complex query to the kitchen team.

Managing New Product Development with Allergen Safety in Mind

New product development at a business like Vanda's Kitchen presents one of the highest-risk moments in the allergen management lifecycle. When a new recipe is created, it may introduce allergens not previously present in the kitchen, require new bought-in ingredients with their own allergen profiles, or create cross-contact risks with existing products. Vanda's Kitchen treats every new product as an allergen event, not simply a culinary or commercial decision. The allergen assessment begins at the recipe development stage — before any production takes place — so that risks are identified and controlled before they reach the kitchen floor.

Each new product passes through a documented allergen review process before it is cleared for production. That process includes a full ingredient-level allergen assessment, a review of every bought-in ingredient's supplier declaration, and a cross-contact risk assessment based on the kitchen's existing production schedule and equipment use. If a new ingredient introduces a new allergen risk into the kitchen environment, the review considers whether additional controls — dedicated equipment, scheduling changes, deep cleaning protocols — are needed before production can proceed safely.

Once a product passes its allergen review, its recipe card and allergen declaration are added to the centralised system before its first production run. This means the allergen matrix and product pages are updated at launch, not retrospectively. Customers, wholesale buyers, and the corporate catering team all have accurate allergen information from day one. It is a discipline that requires coordination between the kitchen, operations, and the team managing the Shopify store — but it prevents the kind of information lag that is often the root cause of allergen incidents at growing food businesses.

Seasonal Ranges, Hampers, and Time-Limited Products

Seasonal trading adds a specific layer of complexity to allergen compliance that many food businesses underestimate. For Vanda's Kitchen, the festive period brings an expanded range of products — gift hampers, limited-edition baked goods, seasonal condiments, celebration cakes — that may only be in production for a matter of weeks. Each of these products requires the same level of allergen documentation as a year-round SKU, despite the compressed development and production timeline. Managing that without a robust system in place would be genuinely difficult at the scale Vanda's Kitchen operates.

Hamper products present a particular challenge because allergen compliance applies not just to each individual item but to the combination of items in the hamper as a whole. A hamper containing multiple products, some with cross-contact risks and some with declared allergens, requires a combined allergen declaration that accurately reflects the full contents. Vanda's Kitchen produces a hamper-level allergen summary for each gift configuration, which is reviewed each time the hamper contents change — and hamper contents often change year on year as products are added, substituted, or discontinued.

For wholesale accounts like Selfridges, seasonal ranges require advance allergen documentation to be submitted as part of the product listing process. This means allergen information must be finalised significantly earlier than for the direct-to-consumer channel. Vanda's Kitchen builds this lead time into the seasonal product development calendar, ensuring that allergen declarations are ready when wholesale buyers need them — not scrambled together at the point of launch when there is far less room to identify and correct errors.

Responding to Allergen Enquiries and Customer Communications

Handling allergen enquiries well is as important as having accurate allergen information in the first place. Customers with allergies are often experienced at asking precise questions, and a vague or poorly informed response — even when the product is in fact safe for them — can erode confidence and cost a sale. Vanda's Kitchen trains its customer service team to treat every allergen enquiry as a high-priority interaction, responding with specific, accurate information drawn directly from the centralised allergen records rather than from memory or assumption.

The business has also developed a set of standard responses for the most common allergen queries — covering the 14 major allergens, the distinction between "contains" and "may contain," and the kitchen's cross-contact controls. These responses are detailed enough to be genuinely useful to a customer who is managing a serious allergy, but written in plain language that is accessible to someone who is simply checking on behalf of a family member or colleague. Having these prepared means responses are consistent, accurate, and fast — even during peak trading periods when the team is under pressure.

For complex or high-risk enquiries — a customer with a severe allergy to a trace allergen, or a corporate client with an employee who has had previous anaphylaxis — the customer service team escalates to the kitchen manager or operations lead who can provide a detailed assessment based on current production records. This escalation pathway is documented and understood by everyone who handles customer communications, so no enquiry falls between teams. It is a straightforward process, but having it explicitly defined makes a significant difference to how reliably it operates in practice.

Keeping Records and Preparing for Inspections

Food businesses in the UK are subject to inspection by local authority environmental health officers, and allergen management is increasingly a focus area in those inspections. Vanda's Kitchen maintains allergen records in a format that can be produced quickly and clearly during an inspection — not because inspections are the primary motivation for good practice, but because the habits that make records inspection-ready are the same habits that make them operationally reliable. Comprehensive, current, well-organised records are a sign of a well-managed allergen system, not just a compliance formality.

Their records include supplier allergen declarations for every bought-in ingredient, recipe cards with allergen assessments for every product, cleaning validation records for production changeovers, staff training records for allergen awareness, and a log of allergen reviews conducted for new products, recipe changes, and supplier changes. Each of these record types is reviewed on a scheduled basis — not just maintained passively — so that gaps or outdated entries are identified proactively rather than discovered during an inspection or, worse, following an incident.

The value of this documentation extends beyond regulatory compliance. When Vanda's Kitchen onboards a new wholesale account that requires allergen declarations, the documentation is ready. When a supplier changes a formulation and notifies the business, the affected products are identified immediately from the records. When a customer makes a complaint about allergen information, the records provide a clear account of what was documented and when. Good allergen records are not a burden — they are the infrastructure that allows the business to operate with confidence at scale.

Lessons for Other Food Businesses

Vanda's Kitchen's approach demonstrates several practices that any food business can adopt:

Centralise allergen data — a single source of truth prevents discrepancies between your kitchen, your labels, and your website
Build supplier management into your allergen process — supplier changes are one of the most common sources of allergen incidents; proactive declaration management prevents them
Publish your allergen information proactively — on your website, in your order confirmations, in your delivery documentation
Separate "contains" from "may contain" — and use precautionary statements only where genuinely warranted
Train everyone, not just the kitchen — allergen safety is a whole-business responsibility
Build allergen review into every change — recipe change, new product launch, new supplier, new equipment — all require allergen assessment
