It does require the proper ingredients and skill to smith your chosen weapons or armor. Without the proper ingredients and perks, you ain't gonna be smithing much in this game.
However you never have to find or experiment to know what the proper ingredients are.
Smithing is like waking up and already knowing exactly how to cook the perfect scrambled eggs, or steak, or even ramen. The process is simply handed to you when you select your Perk.
Alchemy is tasting all your ingredients around you, or buying a cook book and trying what you may think works.
Enchanting is trying someone else's dish and then making an attempt to replicate it.
Yes, crafting has recipes because you need X Ingot + X Leather Strips, but it has no recipes in the sense that you have to actually learn what you are making.
