The idea of cultural appropriation is stupid in the first place. Cultures borrow from one another all the time. If your culture sees something useful from another culture, such as cooking style, easier to build homes, or clothing that is better suited to daily life, there is no reason to not give it a try.
I have tried several ingredients not traditionally used in "white" cooking, simply because they were cheap. I then googled recipes for them. Most of the recipes we're not "white recipes" but saved me money while allowing me to feed my family.
One part of the problem is many have begun to treat culture with an almost religious reverence. It has been exalted and put on a pedestal, often treated as more important than a persons actual morals and values.
