Step 1: Preheat & Prep

1. Preheat oven to 325°F (165°C).
2. Line a baking sheet with parchment paper or grease a loaf pan if making a traditional bread shape.

Step 2: Whip the Egg Whites

1. In a clean, dry mixing bowl, beat the egg whites and cream of tartar using a hand mixer or stand mixer.
2. Whip until stiff peaks form (this should take about 3-4 minutes). The mixture should be fluffy and hold its shape when lifted.

Step 3: Prepare the Cottage Cheese Mixture

1. In another bowl, mix together the blended cottage cheese, egg yolks, vanilla extract, honey (if using), salt, and optional lemon zest or cinnamon.
2. Stir until smooth and creamy.

Step 4: Fold the Mixtures Together

1. Gently fold the egg white mixture into the cottage cheese mixture, a little at a time. Be careful not to overmix—you want to keep as much air in the batter as possible for a fluffy texture.
2. Carefully fold in the blueberries, distributing them evenly.

Step 5: Shape & Bake

1. Spoon the batter onto the lined baking sheet in small round mounds (for cloud bread rolls) or spread it into a loaf pan for a larger bread shape.
2. Bake for 25-30 minutes, or until the bread is golden brown on top and slightly firm to the touch.
3. Remove from the oven and let it cool completely before slicing—it will be delicate when hot but sets as it cools.
