If I, a white man living in upstate NY, were to don Haudenosaunee ritual gear and record myself performing a traditional dance of theirs, that would be cultural appropriation. It refers to a dominant culture taking the trappings of a colonized or otherwise marginalized culture and using them for entertainment, for clout, or otherwise for our own purposes.
On the other hand, if I were to travel to Japan, stay at a ryokan (traditional Japanese inn), and wear the simple kimono they provide for guests, or go to a kimono rental shop and rent a kimono from them for the day, that would be cultural appreciation, because that is something that the Japanese offer openly as a way for foreigners to connect with and understand their culture.
In general, cooking and eating food of another culture in your own home cannot be cultural appropriation. (The only exception I can think of offhand is if the food is part of a closed religious practice of some sort.) Similarly with music—it's very unlikely to be cultural appropriation unless the music is part of a religious practice or being used disrespectfully. Hairstyles and clothing require a bit more nuance and can depend on the situation.
