Savory croissant rolls filled with mushrooms, sunflower seeds, and onions.



Ingredients
Dough
223g (1 cup) sourdough starter
60g (1/4 cup) soy milk
180g (1 1/2 cups) all-purpose flour
1 tbsp sugar
1 tsp salt
28g salted butter, at room temp
Butter Block
225g (2 sticks) salted butter
Mushroom Filling
1 small onion, diced
8oz mushrooms
56g (1/2 cup) roasted sunflower seeds
Instructions
Dough
Mix all of the ingredients except the butter together. Knead by hand or with a stand mixer for at least 10 minutes until a smooth dough forms.
Add in the butter and knead until the dough is able to be stretched thin enough to let light through without tearing.
Place the dough in an oiled bowl, cover it, and let it rise for a few hours until it becomes puffy.
Butter Block Lamination
Roll the dough into a large rectangle. Place the butter block on one side of the rectangle, about 1/2 an inch from the edge.
Fold the dough over the butter block. Press the edges of the dough to seal the butter block inside.
Fold it like a letter: bring 1/3 up and 1/3 down over the middle. Fold the dough in half, cover it, and let it chill in the fridge for at least 30 minutes.
Roll out the dough into a rectangle again. Then, fold it like a vertical letter: bring 1/3 to the right and 1/3 to the left over the middle.
Fold the bottom up, cover the dough, and let it chill in the fridge for at least an hour.
Mushroom Filling
Sautee the onions and mushrooms until most of the mushroom liquid evaporates.
Season with salt and pepper and mix in the sunflower seeds.
Assembly
Roll the dough into a large rectangle. Spread the filling evenly, leaving a small border at the edges.
Roll the dough into a log and cut it into 12 equal pieces. Place the rolls in a greased muffin pan and cover. Place the covered rolls in the fridge to rise overnight.
When ready to bake, preheat the oven to 350 F. Bake for 20-25 minutes or until the rolls are nicely browned.
