    Allergen Matrix

    A structured grid cross-referencing every menu item against all major allergens — showing at a glance which items contain nuts, dairy, gluten, eggs, shellfish, sulphites, and other regulated allergens. The allergen matrix is a regulatory requirement in the EU and an operational necessity everywhere.

    Why Allergen Matrix matters

    EU Regulation 1169/2011 requires food businesses to declare 14 allergens across all food and beverage items. UK Natasha's Law extended this to pre-packaged items. US FDA regulations govern packaged goods; state-level regulations increasingly extend disclosure requirements to restaurant menus.

    Building an allergen matrix manually is tedious and error-prone: someone has to check every ingredient in every recipe against every allergen category, and update it every time a recipe changes. A house orgeat recipe that changes from commercial to homemade (adding almond) needs to trigger allergen updates on every cocktail that uses it.

    The consequences of an inaccurate allergen matrix are not theoretical. Undisclosed allergen reactions are a leading cause of hospitality liability claims globally. In the EU, allergen mislabeling carries criminal penalties in addition to civil liability. The defense 'we updated the recipe but forgot to update the matrix' is not a defense.

    How methodus helps

    methodus auto-generates allergen flags at the ingredient level — when you add an ingredient to a spec, its allergen profile is automatically applied. The allergen matrix updates whenever specs change, not when someone remembers to update it manually.
