This one is like a science trick. Whip egg whites into stiff peaks.
Then fold them into your batter. The trapped air expands in the oven, lifting your bread.
Use 2 whipped egg whites per 1 packet of yeast. This works best for cakes and quick loaves, not crusty artisan bread.
Your bread will be light and cloud-like. Like eating a pillow. A delicious pillow.
Weird history: French chefs used this technique in the 1600s. They called it “whipped snow.” Poetic.
