Modern adaptation
Puerto Rican water bread
Puerto Rican lean yeast bread shaped as two loaves or eight rolls and baked from a cold oven with a pan of boiling water for steam.

Pan de agua is a lean yeast bread associated by this recipe with Puerto Rico. The modern recipe source describes a thin, crackly crust and a light crumb. It makes two long loaves or eight rolls from a simple dough of bread flour, water, yeast, salt, sugar and a small amount of shortening or lard.
This batch uses about 105°F water and a little fat to keep the crumb tender. The author describes the cold-oven steam sequence as the feature that lets the loaves expand before the crust sets. The page also gives a personal childhood association with Aguadilla; that memory does not establish a precise birthplace or a universal formula.
Mix the yeast, sugar, water, flour, salt and shortening into a soft, slightly tacky dough. After kneading, cover and let it rise until doubled, about an hour. Shape it as two long loaves or eight rolls, then leave it covered for 30–40 minutes, until puffy.
The written recipe gives a 25-minute preparation estimate, while its recipe card lists a one-hour total. Those figures do not account for both rises, baking and cooling. This method follows the explicit steps: about 90–100 minutes for the two rises, followed by baking and a 20-minute cool.
Brush the loaves with egg white wash or oil, slash their tops, and set the sheet on the middle rack of a cold oven. Put a metal pan on the lower rack, pour in two cups of boiling water, close the door, and turn the oven to 400°F. Do not preheat or open the door for the first 25 minutes.
The written method bakes loaves for about 30–35 minutes total and rolls for 20–25 minutes. It uses deep color and a hollow sound as its cues, but gives no internal bread temperature. Cool the bread on a rack before slicing.
Do not taste the uncooked dough. FDA warns that raw flour can carry harmful bacteria and recommends washing hands, bowls, utensils and surfaces after handling it. The steam pan contains boiling water: pour it carefully with your hands and face clear, then close the oven door at once.
No proofing temperature or internal bread temperature is provided. The method's oven setting, steam sequence and bake cues are recorded as recipe instructions; they are not presented as validated safety limits.
The inspected modern recipe identifies itself as Puerto Rican pan de agua and places the author's personal childhood experience in Aguadilla. Its account of an island-wide bread style and cold-oven method is attributed to the recipe author; no dated earliest attestation or exclusive origin is established here.

Flour may carry harmful bacteria; the dough must be cooked before eating.
Hazard sourcePouring boiling water into a pan inside the oven creates hot steam and can burn hands or face.
Hazard sourceDo not taste raw flour or dough. Wash hands, bowls, utensils and surfaces after handling flour and raw dough.
Control sourceUse a stable metal steam pan, keep hands and face clear of the steam path, pour carefully, and close the oven door immediately.
Control sourceThe source gives crust color and a hollow sound as its bake cues but no internal bread temperature. These cues are part of that method, not a measured safety limit.
The recipe card's one-hour total does not match the explicit rise, bake and cooling steps; the instructions and timing here follow the written steps.
The inspected recipe identifies this batch as Puerto Rican pan de agua and describes the author's personal experience growing up with it in Aguadilla. This is a country-level recipe association, not a precise origin claim.
