Building an accurate allergen matrix means checking every ingredient in every dish against a supplier spec sheet or label, not guessing from the recipe name. Teams routinely underestimate the job because they count dishes rather than ingredients, then run out of time halfway through and publish a matrix with gaps. Knowing the real size of the audit up front lets you schedule it properly and finish it.

The estimator multiplies dishes by ingredients per dish, removes the share of ingredients that repeat across dishes, and applies the minutes each unique ingredient takes to verify. Matrix cells are dishes times allergens tracked. Monthly upkeep assumes every recipe change re-checks the full ingredient list of that dish. It does not add time for chasing missing supplier documents, which is often the slowest part of the job.

How to use this tool

  1. Count the dishes on your menu, including sides, sauces served on their own, desserts and drinks with ingredients.
  2. Estimate ingredients per dish from a few typical recipes and the share of ingredient lines that repeat across the menu.
  3. Enter minutes per ingredient check, the allergens you track and your typical recipe changes per month, then read the audit hours and monthly upkeep.

What the math assumes

  • Unique ingredients equal dishes times ingredients per dish, reduced by the shared percentage you enter; the estimator cannot see your actual recipes.
  • Every unique ingredient takes the same number of minutes to verify against a spec sheet or label, and recording the matrix cells is included in that time.
  • Matrix cells are simply dishes times allergens tracked; the default of 9 reflects the nine major food allergens under US federal labeling law and can be changed.
  • Each recipe change re-checks the full ingredient list of one dish, even if only one ingredient moved.
  • Time spent requesting missing spec sheets from suppliers, training staff or reviewing cross-contact in the kitchen is not included.

Frequently asked questions

Why count ingredients instead of dishes?

Because allergens live in ingredients. A dish with twelve components needs twelve checks, and a bought-in sauce can hide sesame or soy that never appears in the recipe name.

How do I estimate the shared ingredient percentage?

Pick five dishes, list their ingredients, and count how many lines appear in more than one dish. Kitchens with a tight pantry often share heavily; menus built on many bought-in items share less.

Should I count sub-recipes as ingredients?

Audit each sub-recipe once as its own item with its own ingredient list, then count it as a single ingredient line wherever it is used. The shared percentage is what accounts for that reuse.
