I've recently come across and tried a few recipes ( mostly Indian) where instead of sautéing the garlic , onion ( and sometimes ginger) first, they are added raw into a blender with tomatoes and other stuff, and eventually added to the dish to cook down in the pan ( basically boiling). Any time I do this , I get a certain bitterness or unpleasant taste when compared to if I sautéed those ingredients first. I know these ingredients have different flavors depending on how they are cooked ( fried, boiled , caramelized , baked .. whatever method), I just find them unpleasant when blended up raw and tossed into a sauce. I know usually when cooked, these ingredients lose a lot of their raw potency, but I find the above method just transforms them into an unpleasant taste. The bad flavors dont change during the cooking process. Just curious if maybe Im doing something wrong. I've seen it in other cuisines as well, but I recently came across it in a few Indian dishes.
