This sourdough brioche recipe yields a soft, buttery loaf with a delightfully tangy flavor. Tangzhong (cooked flour paste) is used to enhance the bread’s moisture and tenderness. This bread is perfect for french toast or bread pudding!
1. Whisk flour and water in a saucepan until smooth. Cook over medium heat, stirring constantly for 2-5 minutes until a paste forms. Transfer the tangzhong to a heat-safe container, cool completely before adding to the dough. Can be prepared 1-2 days ahead.
2. Crack the egg into a small bowl and then add 2 teaspoons of water to the bowl with the egg. Use a fork or a small whisk to beat the egg and water together until its well combined.
3. In a large bowl or stand mixer bowl, combine the sourdough starter, slightly cooled milk, sugar, eggs, and tangzhong. Combine these ingredients using clean hands, a hand mixer or the paddle attachment on low speed if you’re using a stand mixer.
