To me, taste and texture are of approximately equal importance. I find that I crave food according to texture rather than taste. I really like sour foods more than other people do; I can eat a lemon like an orange. Unlike some here, I love lumpy mashed potatoes, and I don't like foods that are just mush with no texture, unless they taste really good, like butterscotch pudding, mmmmm. I can't stand bitter tastes: coffee, pickles, olives, ugh, even though I like to imagine what pickles would feel like to eat because they are so nice and crunchy. I like it best when all the different foods are clearly separated on my plate, unless it is sauce that is supposed to be poured on top and then it's ok. Once I got my diagnosis, that weird preference had an explanation.
One time, I had some weird sinus infection, and, after the initial stuffiness, I had no other symptom than I completely lost my senses of taste and smell. That was a weird couple of weeks. I could have eaten or drunk anything that I didn't like the taste of, but I was so freaked out that I wouldn't be able to tell if the food I was eating had gone bad, so I kept to my normal diet and had to make do with just the textures. I think that just having the tastes without the textures would be even weirder (I think that crunching stuff with my teeth is one of my stims, and I definitely have an oral fixation). I supposedly (according to skin tests) have various mild food allergies, such as tomatoes, but I really like them and I still eat them. My allergist said that we often crave the foods we are allergic to, but I guess it could work the other way too, especially if the allergy causes digestive problems (which it doesn't for me).
I think the texture thing might have to do with AS, but the taste thing possibly not.
