That's an interesting comparison - I've never thought of cultural appropriation along the lines of FOSS licenses before (I guess because the rules for borrowing from other cultures are unwritten). I wonder what compliance should look like in this case - is it enough for the borrower to treat the borrowed dish with care and make an earnest attempt to create something that respects the culture of origin (E.g., don't make steak tikka masala)? Should there be a note on the menu "this dish is inspired by the traditional food X, from culture Y"?
