Atole agrio
A hot, sour maize drink from Tabasco made from maize that is not lime-cooked. The ground grain sours for half a day, then makers strain it and boil it until thick.
Small, lightly enriched rolls with tapered ends and a scored top; this six-roll formula bakes on a hot stone with steam for a thin, crisp crust.

King Arthur Baking describes bolillos as small rolls made and eaten throughout Mexico and Central America. The publisher notes their thin, crisp crust and tender crumb, and their use in tortas. This page follows one formula from The Big Book of Bread; it does not treat that formula as universal or assign a precise birthplace.
The batch makes six rolls from about 150 g of dough each. The shaped rolls are elongated with tapered ends and scored once along the top. Baking on a preheated stone with steam in a hot skillet helps produce the crisp crust described in the recipe. The method specifies two proofing windows and a total time of about three hours, but gives no target dough or room temperature for the rises.
Adding water to a hot cast-iron skillet creates a sudden burst of steam. Dry oven mitts and a clear space around the oven help keep hands and face away from the hot cookware and steam. The crust softens in storage, so the recipe recommends eating the rolls on baking day; it gives no storage duration.
King Arthur Baking says bolillos are made and eaten throughout Mexico and Central America and presents this formula from The Big Book of Bread. The record describes that one contemporary published batch; the source does not identify a city of origin or claim one formula is used everywhere.

Hazard sourceDo not taste the raw dough. Bake the rolls as directed, and wash hands, bowls, utensils and work surfaces after handling raw flour or dough.
Control sourceUse dry oven mitts to handle the hot stone and skillet. Keep your face and hands away from the escaping steam when carefully pouring water into the hot skillet.
Control sourceThe source's crust colour and feel are baking cues, not validated internal-temperature checks.
Only use oven equipment and steam methods that are safe for the oven and cookware being used.
The source states that bolillos are made and eaten throughout Mexico. It does not identify a city of origin or claim this single formula is universal.
