You’re baking delicious pumpkin pie cake bars. Everything is mixed in, poured into the baking dish, put in the oven. Two minutes later, while wiping the counter, you see a can of pumpkin, unopened, shiny… your brain thinks… what exactly is in the oven right now? Then overdrive… pull out the dish, and realize, yes, it’s lighter than normal! Fortunately, it’s not cooked, just slightly warm. You energetically mix in the pumpkin and reinsert the dish in the oven.
Moral: Don’t forget the main ingredient!
