# What You'll Need:
→ 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 gel food coloring
07 - Yellow gel food coloring
08 - Blue gel food coloring
09 - Green gel food coloring
# Directions:
01 - Preheat oven to 300°F. Line a baking sheet with parchment paper.
02 - In a large bowl, use an electric mixer to beat egg whites and cream of tartar until soft peaks form. Gradually add granulated sugar, continuing to beat until stiff and glossy peaks are achieved.
03 - In a separate bowl, whisk together egg yolks, cornstarch, and vanilla extract until smooth and uniform.
04 - Gently fold the egg yolk mixture into the whipped egg whites using a spatula, being careful to maintain the light texture.
05 - Divide the mixture evenly into four bowls. Add several drops of desired gel food coloring into each bowl and gently fold until the color is thoroughly incorporated.
06 - Spoon the colored mixtures onto the prepared baking sheet in adjacent dollops to create a rainbow effect. Swirl together lightly with a spatula for a marbled appearance if desired.
07 - Place the baking sheet in the oven and bake for 25 minutes, until set and lightly golden.
08 - Let cool on the baking sheet for several minutes, then carefully remove. Serve immediately for optimal fluffiness.
