I've just started studying baking ratios. I like to learn to cook/bake on Youtube, and as I've been analyzing alot of the cooking/baking ratios I notice that quite a few of these youtube chefs do not follow the baking ratios. For example, in a muffin recipe, instead of the 2:2:1:1 ratio with flour:liquid:fat:egg, it was a 1:.6:1 (no liquid but add sugar) ratio (flour:butter:egg). Also does a ten percent deviation between ratios make a major difference? I also noticed that most people are making cupcakes when they make muffins.
Also: Does something like cream cheese fall under a "fat"?
