How is a 'local dish' defined in cases where necessary inputs like salt or sugar must be imported?

Answer

By the proportion of ingredients that are locally derived, or by the specific, local modification made to the recipe using imported staples.

When necessary inputs cannot be sourced locally, the dish is defined by the ratio of local ingredients used or the specific local adaptation applied to a recipe using imported staples.
