Margarine and shortening are not the same, and that is wonderful news. It means you have choices, and each choice leads to a different, delightful destination. You are not just following a recipe; you are composing it.
So next time you walk into the kitchen, don't see a pantry filled with confusing fats. See a palette of possibilities. You have the power to create anything from a sky-high biscuit to a delicate, thin wafer. Isn't that inspiring?
Keep baking, keep experimenting, and never stop asking "why?" The more you learn, the more magical (and delicious) your kitchen becomes. Now go make something that makes you smile!
