I froze away some of my first sourdough starter, last year, and pulled out 2 oz which I rehydrated and fed a few days earlier.
Then, I made some rolls with it. I had intended to make hamburger buns but for some reason, changed my mind and ended up placing the dough balls into an oiled 9 by 13 inch glass baking dish and made rolls instead. Since I don’t have a scale accurate enough to weigh small quantities, I ended up with some large balls of dough and after removing the excess, ended up with enough dough to make a single perfect hamburger bun.
The bun makes a great sandwich. The crumb of the rolls is light and fluffy.
Hybrid Brioche Cheddar Cheese Hamburger Buns/Rolls – makes 2 1/2 lbs/1.1 kg dough, enough for 16 buns
1 1/2 tsp dry active yeast
3/4 cup warm water (replace with water and 1 tbsp milk powder or 2 % milk for a brioche)
1 tbsp sugar
1 1/2 tsp salt
1/4 cup melted butter
1 cup active sourdough starter
2 eggs, plus an extra egg for egg wash
~ 1 cup shredded cheddar cheese
4 – 4 1/4 cup all purpose flour
Poppy or sesame seeds for topping (optional)
In a medium sized bowl, dissolve the sugar in warm water. Sprinkle in the yeast, stir and let sit for 5-10 minutes until foamy.
In a large bowl, add 2 cups of flour, salt, melted butter, 2 eggs and the sourdough starter.
Mix well with a large wooden spoon until you get a batter like consistency. Add the cheese and mix through. Gradually, add the rest of the flour, about half a cup at a time until the dough starts forming a ball in the bowl.
Transfer the dough to a floured working surface and add additional flour until you get a soft dough. Knead for about 10 minutes.
Turn dough out into an large oiled bowl and cover. Let rise in a warm place until doubled in size, which will take about 1 -1 1/2 hrs.
Divide the dough into 16 equal portions and form into balls.
Prepare 2 baking sheets by lining with parchment paper or brushing with vegetable oil. Spread out 8 balls of dough over each of the baking sheets so they’re at least 1 1/2 inches apart.
Cover and let rise in a warm place until doubled in size.
Preheat the oven to 425 deg F.
Beat the extra egg with a tablespoon of cold water and, using a pastry brush, brush over the top of the buns. If using the dough for buns, after letting them rise, pat them down a bit, gently, to get a wider bun.
Sprinkle poppy or sesame seeds over the top of the buns if desired.
Bake the buns for 12-17 minutes or until the tops are a golden brown and the bottoms are browned as well.
Transfer to a cooling rack.
