# 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 (optional, for stability)
05 - 1/4 teaspoon vanilla extract
→ Color Additions
06 - Red, yellow, blue, and green gel food coloring (or preferred assortment)
# Method:
01 - Preheat oven to 300°F (150°C). Line a baking sheet with parchment paper to prevent sticking.
02 - In a large, clean mixing bowl, beat egg whites and cream of tartar using an electric mixer until soft peaks begin to form. Gradually add sugar, continuing to mix until stiff and glossy peaks are achieved.
03 - In a separate bowl, whisk together the egg yolks, cornstarch, and vanilla extract until the mixture is smooth and homogenous.
04 - Carefully fold the egg yolk mixture into the whipped egg whites with a spatula, taking care to preserve the aeration.
05 - Divide the batter evenly into separate bowls, corresponding to the desired number of colors. Add a few drops of gel food coloring to each bowl and gently fold until the color is uniform.
06 - Spoon the colored mixtures onto the parchment-lined baking sheet, side by side, to form a rainbow pattern. For a marbled effect, swirl the colors lightly with a spatula.
07 - Place the baking sheet in the oven and bake for 25 minutes, or until the surface is lightly golden and the bread is set.
08 - Remove from oven and allow to cool for a few minutes before lifting off the baking sheet. Serve immediately to enjoy optimal fluffiness.
