# Ingredient List:
→ Egg Mixture
01 - 3 large eggs, separated
02 - 3 tablespoons granulated sugar
03 - 3 tablespoons cornstarch
04 - 1/4 teaspoon cream of tartar
05 - 1/4 teaspoon vanilla extract
→ Color Additions
06 - Red, yellow, blue, and green gel food coloring
# Steps:
01 - Preheat the oven to 300°F (150°C). Line a baking sheet with parchment paper for nonstick results.
02 - In a large, clean mixing bowl, beat egg whites with cream of tartar until soft peaks form. Gradually incorporate sugar while beating until stiff, glossy peaks are achieved.
03 - In a separate bowl, whisk together egg yolks, cornstarch, and vanilla extract until the mixture is fully combined and smooth.
04 - Carefully fold the egg yolk mixture into the whipped egg whites using a spatula, preserving the airy texture.
05 - Divide the batter equally among multiple bowls. Add a few drops of desired food coloring to each portion and gently fold to incorporate without deflating.
06 - Using a spoon, arrange colorful batter dollops side by side on the prepared baking sheet. For a marbled rainbow look, swirl gently with a spatula.
07 - Transfer to the oven and bake for 25 minutes, until set and lightly golden.
08 - Let cool for several minutes before lifting off the baking sheet. Serve immediately to maintain optimal fluffiness.
