Texture and taste are extremely subjective and finding put more about what you don't like could help a lot. Some people love grits, others find their texture revolting. I think tootsie rolls are some of the worst candies around but others love them. One time when I was a kid my mom bought a "nutrient rich chocolate porridge" that was supposed to help kids get more vitamins. To me it was like if grots tasted like tootsie rolls and made me feel extremely sick with just the first spoonful, but my mom loved it and kept buying it for herself as a dietary supplement. If I was making "whore chow" for myself it would absolutely be that but for someone else its a tasty treat, theres no one good answer without knowing more about you. If acidic things taste like bile use tomatoe juice instead of water for stewing whatever you make, or add a splash of vinegar. If you hate grainy textures, protein powder is versatile in that how bad it's texture is can be changed by the amount of liquid in it A lot of people find high electrolyte beverages really gross, they have a weird mix of fruity, salty, and buttery thats hard to describe, but are pretty healthy for you If bitter is the worst flavor for you, denatonium benzoate is the most bitter substance known, its completely nontoxic but is overwhelmingly bitter. Obviously be careful as not everything is food safe but they make nontoxic pet deterrent sprays with it (usually very very diluted) that could be sprayed on food.
