Okay, I thought I knew how the whole profit thing worked, but apparently I don't. So can someone explain to me how the heck I figure out what the best food to cook is? Originally I thought it was like the profit per serving making Angel Food Cake the best (up to level 22), but then I thought maybe it's the income per minute but that makes brownies the best and I've seen everywhere that Red Velvet Cake is the best.

I hope this question makes sense. Thanks, guys.
