Step 1: Grease with Shortening
Fold a sheet of paper towel and dip it into the shortening. You’ll need plenty, so go ahead and scoop out a big gob of the stuff. Then, as though washing the pan with a soapy sponge, spread the shortening around, making sure to coat all of its nooks and crannies.
Step 2: Dust with Flour
Next, take a spoonful of flour and lightly dust the greased pan. Next, pick up the pan, gently tapping and rotating it to create a thin, even coating of flour across the pan’s interior.
Step 3: Tap Away the Excess
Time to shake out any excess flour. Head over to the sink or wastebasket, turn the pan upside down and gently tap. If you see any missed spots after tipping the pan over, just go back over with a bit more shortening and some flour.
What if You Don’t Have Shortening?
A cooking spray just for baking, one that’s formulated with flour. It’s a good substitute.
