My mother refers to a "bite" as in something to bite on, say raw carrot bits in a stew.
Cambridge only refers to the food sense noun as a strong taste, though:
bite noun (STRONG TASTE) › [U] If food has bite, it has a sharp or strong taste: I like mustard with bite.
That still applies if it were pickles in a tuna salad, but can "bite" also refer to food texture alone? I think it might be more versatile than "crunch" or "chewy".
What is the best word to describe under-cooked carrot bits in a stew, as well as pickle bits in a tuna salad?
