What does do about this?

Each recipe that you will consult on the site will present you with the list of allergens that it is possible to encounter depending on the ingredients it contains.
We indicate "possible" because it also depends on the origin of your ingredient.
An example: Using raisins in a recipe will bring up the allergen "sulphites", but this is not a certainty, it depends on your raisins and the way they were produced.
