Nutrient profiles and flavor management is stuff the pros do and requires book learning - specifically food science. There are multiple sources here you can dig into, from videos to multi-volume encyclopedias on cooking. You don't need this per se to be a home cook, but it takes you from recipe bound retard to "able to whip anything up" level of skill. The alternative to book reading is just to cook a whole fuck ton of recipes, modify them, and then branch off into doing your own shit.
