I made a dozen of those brioche-style treats, and I froze half of it.
- 40g brown sugar
- 40g white sugar
- 20g fresh yeast
- 400 to 500g flour (150g of it was bread flour)
- 60ml milk
- 1 egg
- 1 yolk
- 1/2 vanilla pod
- ground nutmeg
- sea salt
- 1 small tbsp rum
- 120/150ml mashed sweet potatoes (take 250g sweet potato, cook them for 8 minutes in the microwave until soft and mash the flesh with a fork)
- 25g butter
Melt butter in a small skillet. Let it cool.
Slightly heat the milk, but don't bring it over 105°F because you'd kill the yeast. It must be a bit warmer than lukewarm, put it in a bowl with fresh yeast and let it sit for 5 minutes.
Add sugar, brown sugar, pinch of salt, vanilla seeds, a pinch of grated nutmeg, rum, and whisk to combine.
Add mashed sweet potato, butter, egg and yolk and whisk until incorporated.
Add flour, first put 200g and add a bit more as it is incorporated until you have a dough thick enough/not too sticky to be shaped into a ball (knead at least 5/7 minutes).
Let it rise for at least 2 hours on countertop, cover with a clean cloth.
Knead slgightly then roll the dough about 1.5cm thick, cut doughnuts (don't forget the holes) and place them on a baking sheet to let them rise again for 2h covered. You can use molds but it's not compulsory.
Preheat the oven to 200°C (400°F) and bake for about 10 minutes until you get a nice color.
Sprinkle with icing sugar and enjoy !
