Is crafting a main part of the game? I have never enjoyed having to farm materials and craft things, I always find it tedious to me. Even though I beat skyrim like 3 or 4 times I never crafted anything because it's never been fun to me.
Only to the point that you want to focus on it. For me, crafting was simply looking up a recipe or two online for weapons primarily and then creating it. Most of them are very simple though where you need for instance 2x an item that drops every time you kill a mob of xxx and then a piece of linen cloth and another item which is everywhere.
Food wise you COULD go crazy and craft as much as you want, I stuck to just creating jerky for mostly the entire game which is just 2 salts and 2 pieces of meat and that creates 5 jerky to use in battle. I am not one to scavenge and scrounge for things for crafting either and I still enjoyed it. Most of the good gear I found was in bandit camps or dungeons I found around the world.
