Ingredients

8 servings

1 cup (240g) unfed sourdough starter discard (room temperature)
2.5 cups (300g) bread flour (or all-purpose flour)
½ cup (120ml) whole milk, warmed (105°F / 40°C)
3 tbsp (45g) unsalted butter, melted & 2 tbsp sugar
1.5 tsp instant dry yeast & 1 tsp fine sea salt
2 large eggs (1 for dough, 1 beaten with 1 tbsp milk for egg wash)
2 tbsp white sesame seeds or poppy seeds

Step-by-Step Instructions

In a bowl, **whisk warm milk, instant yeast, sugar, 1 egg, and sourdough discard**. Add flour and salt; knead on a floured surface for 6 minutes. Knead in melted butter until dough is smooth and soft.

Divide dough into 8 equal balls (approx 85g each). **Roll into smooth balls and press down with your palm to flatten into 3.5-inch disks** on a parchment-lined baking sheet. Rest in a warm spot for 20 minutes.

Preheat oven to 375°F (190°C). **Brush flattened dough disks generously with egg wash** and sprinkle toasted sesame seeds over top.

Bake at **375°F (190°C) for 16 to 18 minutes** until tops are deep golden brown. Transfer to a wire rack, cool 15 minutes, slice in half, and toast for burger night!

Chef Amara’s Kitchen Secrets & Pro Tips

Chef's Secret Flattening Step: Press round dough balls into 3.5-inch flat disks so they bake into wide burger buns instead of tall rolls.
Egg Wash Gloss: Brush dough twice with egg wash for a high-gloss bakery shine.
Toast Cut Sides in Butter: Toast sliced buns in a buttered skillet for 1 minute to prevent burger juices from soaking through.

1. Spoon and Level Your Flour: Never scoop flour directly from the canister with your measuring cup, which packs excess volume by up to 25%. Fluff the flour with a fork, spoon it into the cup, and level the top with a knife. 2. Season in Measured Layers: Introduce small pinches of salt at different cooking stages rather than dumping seasoning on at the end. This draws out moisture and seasons every ingredient to its core. 3.
