What’s your favorite food, and what’s the most efficient?

Im used to games where optimizing every aspect of gameplay is normal. Now that I’ve almost 100% Palia, what is the most efficient food to eat, and what’s your personal favorite? When I say efficient, I mean what required the least amount of ingredients for the most focus? I personally put 30 star apples in my Preserves machine, and subsist almost purely on star apple jam, I’m looking to change my ways.
