Conchas

Step 1

Make the dough: In the bowl of a stand mixer fitted with the dough hook, combine yeast, water and milk. Add 1 teaspoon granulated sugar and let sit until foamy, 5 to 10 minutes.

Step 2

Add the remaining 1/2 cup granulated sugar, the butter, salt, eggs and flour. Mix on medium speed until the dough forms a smooth, elastic ball that pulls away from the bowl. It should be just a little bit sticky, not completely dry like bread dough. Use your hands to lightly coat the dough ball with the oil, then return it to the bowl. Cover with a dish towel and set aside to rise in a warm place until doubled, about 2 hours.

Step 3

When the dough has risen, butter two baking sheets. Punch the dough down lightly and use a knife or bench scraper to divide it into 12 balls (75 to 80 grams each). Arrange on the buttered baking sheets.

Step 4

Make the topping: Combine the ingredients in a medium bowl and use your fingers to mix and rub together until the mixture has the consistency of cookie dough. Divide the topping into 12 balls (each one will be about 13 grams, if you want to be exact about it). One by one, use your fingers to press and pinch each ball into a thin circle about 3 inches across. (You could also do this on a work surface, placing the ball between two pieces of parchment paper).

Step 5

Drape a flattened topping circle over the top of each bun, completely covering it. Lightly press any loose edges into the sides of the bun, making a snug coat on top.

Step 6

To make a shell pattern, use a sharp knife to slash parallel lines in the topping over the top of each bun — or you could make a spiral pattern, or score the tops in a criss-cross diamond pattern. Cover with a dish towel and set aside in a warm place to rise for 30 minutes.

Step 7

Meanwhile, heat the oven to 375 degrees. Bake buns until lightly browned on the tops and sides, about 20 minutes, rotating the pans after 10 minutes.

Step 8

Serve warm, or let cool and store overnight in an airtight container. Reheat gently or serve at room temperature.
