Once a sub-recipe contains ingredients, its allergens and dislikes are inherited automatically: on save Sprwt collects every allergen and dislike from the ingredients listed and stores the union on the sub-recipe, and the Allergens / Dislikes section is hidden in the form. To change them, edit the underlying ingredients. Whenever an ingredient's allergens or dislikes are changed (even inline in the list), all sub-recipes containing it are updated as well. A sub-recipe with no ingredients yet keeps whatever allergens/dislikes you pick manually.
