Does rich also mean savoury? If so then yes. I also voted sweet, sour, spicy and salty. Salty is a either a hard yes or no depending on the food. There are some foods I cant stand having salt on them. Spicy is one of my favourites. I love practically every kind...Mexican, Indian, Thai, and especially the curries. Sour is good as long as its sort of fruity, like lemon flavoured stuff. Sweet is good on almost anything especially ice cream. Cant have too much sugary things because of my sensitive teeth but I love most sweets and desserts.
