If your food tastes better all mixed together like that then your food tastes like shit. Eat better stuff and you'll want to taste things in the normal way.
when i was younger i had a serious issue with non-complimenting foods touching on my plate. i would get extra plates or bowls so my foods didnt touch each other. and if they did, i wouldnt eat them.
im not quite that bad anymore, but i still prefer that foods stay in their own little areas on my plate.
yes, i am aware that this is probably a sign of some sort of mental disorder.
dont even get me started on candy like skittles or m&ms. >.>
It's always separated, unless it's something like beans and rice, or mashed potatoes and peas.
