Why an accurate matrix matters
An out-of-date allergen chart isn't an admin problem — it's a safety one. The 14 regulated allergens have to be declared correctly every time a customer asks, and a single wrong answer can put someone in hospital. Under Natasha's Law, food prepacked for direct sale (PPDS) must also carry a full ingredient list with those allergens emphasised, so the data behind your matrix has to be right and easy to reach.
Blueroll keeps that data in one place: every dish mapped against all 14 allergens — celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, tree nuts, peanuts, sesame, soybeans and sulphur dioxide (sulphites) — alongside dietary flags your front-of-house team can read at a glance.
It stays current when recipes change
Most matrices go stale the moment a recipe changes — someone swaps an oil or adds a garnish, and the chart on the wall no longer matches the plate. Because Blueroll builds the matrix straight from your recipes, editing a recipe updates the matrix automatically. There's nothing to re-type, and no second document to keep in sync.
Importing your menu is fast too: with AI recipe import, recipes and their ingredients drop into Blueroll in seconds, and their allergens feed the matrix from day one.
Frequently asked questions
What is an allergen matrix?
A chart listing every dish on your menu against the 14 allergens you must declare under UK and EU law. It shows at a glance which allergens each dish contains, so staff can answer customer questions accurately and consistently.
Does Blueroll cover Natasha's Law (PPDS)?
Yes. Because the matrix is built from your recipes, the allergen and ingredient data you need for PPDS labelling and front-of-house reference is already in one place — and it stays accurate as recipes change.
Can I export the allergen matrix?
Yes. Print it for a front-of-house folder or export a PDF to email your EHO. The export covers all 14 allergens plus the dietary labels for each dish.
