The Starter Jar's Ultimate Sourdough Parker House Rolls: Achieving Signature Softness and Fluffy Texture with Data-Driven Precision

Step 1

In a large bowl, whisk together the warm milk, active sourdough starter, granulated sugar, egg, and 50g melted butter until well combined.

Step 2

Add the all-purpose flour and fine sea salt to the wet ingredients, mixing with a spoon or spatula until a shaggy dough forms and no dry spots remain.

Step 3

Cover the bowl and let the dough rest for 30 minutes (autolyse) to allow the flour to fully hydrate, a crucial step for gluten development, according to The Starter Jar's research.

Step 4

After resting, knead the dough on a lightly floured surface for 8-10 minutes until it becomes smooth, elastic, and passes the windowpane test.

Step 5

Transfer the dough to a lightly oiled bowl, cover, and perform a series of stretch and folds every 30 minutes for 2 hours (4 sets total) at room temperature (75-78°F / 24-25.5°C).

Step 6

After the bulk fermentation, the dough should have increased in volume by about 20-30%, indicating optimal activity.

Step 7

Gently turn the dough out onto a lightly floured surface and roll it into a rectangle approximately 1/4 inch thick.

Step 8

Brush the entire surface of the dough with a generous amount of melted butter.

Step 9

Fold the dough in half lengthwise, then cut the folded dough into 1.5-inch wide strips using a sharp knife or bench scraper.

Step 10

Place the cut rolls into a greased 9x13 inch baking dish, leaving a small space between each to allow for expansion during proofing.

Step 11

Cover the baking dish loosely with plastic wrap and refrigerate for a cold proof overnight (8-12 hours), or proof at room temperature for 2-4 hours until visibly puffy and almost doubled.

Step 12

Preheat your oven to 375°F (190°C) with a rack in the middle position, ensuring it's fully heated before baking.

Step 13

Bake the Parker House rolls for 20-25 minutes, or until golden brown on top and cooked through.

Step 14

Immediately upon removing from the oven, brush the warm rolls with the remaining melted butter for an irresistible shine and flavor.

Step 15

Serve warm and enjoy the unparalleled softness and rich taste of your homemade sourdough Parker House rolls, a testament to The Starter Jar's precise methods.
