As you may have noticed, I have been turning to mashed potatoes in more and more in my baking. In this recipe, they stand in for 5 eggs and give the final product a soft texture but also a durable structure that holds plenty of air pockets. The other thing that makes this recipe perfect is homemade vegan butter (you can use Earth Balance, of course, but I find it leaves an aftertaste (and you need to reduce the salt in the recipe by at least half)). I make it by the triple batch (blending it in a juice pitcher with my immersion blender) which fits perfectly into this pan. This recipe is a veganized version of Peter Reinhart’s “Middle-Class Brioche,” which you can reference in The Bread Baker’s Apprentice if you want more direction. It is easiest to do this with a stand mixer, but a spoon and some elbow grease will also do the trick.
INGREDIENTS
Sponge
– 2.25 oz bread flour
– 2 tsp instant yeast
– 4 oz lukewarm soy milk
Dough
– 4oz mashed yellow potato (i.e. whole potato boiled in its skin, cooled, peeled, and mashed)
– 1 tbsp finely ground yellow flax
– 4 oz soy milk
– 1/4 tsp turmeric (optional, for colour)
– 13.75oz bread flour
– 2 tbsp sugar
– 1 1/4 tsp salt
– 8 oz vegan butter, a room temperature
– soy milk for brushing
METHOD
Sponge
1. Mix together sponge ingredients until four is well hydrated. Cover and let sit for 45 mins.
Dough
1. Blend together mashed potato, flax, and soy milk (and turmeric if using) with an immersion blender in a 4 cup measuring cup until smooth. Warm in the microwave to room temperature.
2. Mix together flour, sugar, and salt in a mixing bowl. Add all of the sponge and the potato mixture and bring together into a dough. Let the dough sit for 5 mins.
3. Using the paddle attachment on a mixer, add in 1/4 of the butter, waiting until the previous amount has been fully incorporated before adding more. The final dough will be smooth, satiny, and soft.
4. Transfer the dough to a baking sheet lined with greased parchment paper. Lightly mist the dough with oil, then cover and refrigerate for at least 4 hours.
5. Spray a muffin tin lightly with oil. Or brioche tins.
6. When dough is ready to be baked, divide it into 12 equal pieces. Shape per this video. Place in the prepared tin(s).
7. Cover and let rise for 1.5 to 2 hours, or until the tins are filled. Preheat oven to 400 degrees.
8. About 15 mins before baking, gently brush the brioche with soy milk.
9. Bake for 15-18 mins, or until golden brown. Carefully remove from the tin(s) and let cool before eating.
