Try this Spanish Hard Rolls (Bolillos) recipe.
Bakers frequently err by under-kneading the dough before the initial fermentation phase, which prevents the gluten network from developing the necessary elasticity to trap gas effectively. Bread flour contains a higher protein content than all-purpose flour, supplying the structural foundation required for these substantial rolls. When you switch from the flat beater to the dough hook after two minutes, the machine begins organizing the tangled protein strands into parallel sheets that stretch without tearing.
Because bread baking relies on moisture evaporation and starch gelatinization rather than a specific internal target, visual cues remain the most reliable indicator of doneness. You must monitor the exterior color closely, baking the shaped pieces until the crust turns a uniform golden brown across the entire surface. Brushing a mixture of cornstarch and water over the unbaked dough creates a glossy starch film that gelatinizes in the heat of a 375 degree Fahrenheit oven, yielding the characteristic hard, crackling crust. When tapped firmly on the bottom, a fully baked loaf produces a hollow sound that signals the interior moisture has properly escaped.
