Minho and Trás-os-Montes, Portugal
The traditional yeasted cornbread of northern Portugal — dense, slightly sour, with a thick, darkened crust and a moist, tight crumb. Broa (from the Latin brace — fermented grain) uses maize flour (farinha de milho) combined with rye or wheat flour, warm water, and a natural leavening. It was the daily bread of the peasants of Minho and Trás-os-Montes from the 17th century when maize arrived in Portugal from Brazil. Broa is indissociable from caldo verde (which is always served with it), bacalhau preparations (the crumbled broa crust for bacalhau com broa), and acorda. Its dense, tight crumb absorbs soups without disintegrating — a critical functional property.
Combine maize flour with rye or wheat flour in a ratio of approximately 2:1 maize to rye/wheat. The maize flour must be scalded with boiling water before combining — this gelatinises the starch and produces the characteristic dense, moist crumb. Natural leavening (either sourdough starter or commercial yeast) is used. Shape into a round ball (bola) and bake at high heat (220°C) for 45-60 minutes. The crust must be dark and firm — pale broa is underbaked.
Day-old broa is better than fresh for most cooking applications — it firms and dries slightly, making it ideal for crumbling over bacalhau or soaking in açorda. The best broa in Portugal comes from small village padarias (bakeries) in Minho where sourdough culture has been maintained continuously for generations. The Broa de Avintes (IGP) from a village near Vila Nova de Gaia uses exclusively maize flour and is the densest, most extreme version. Pair with caldo verde, sardines, or Vinho Verde.
Not scalding the maize flour — produces a grainy, dry crumb. Under-baking — the thick crust is the structural element. Using only maize flour without a wheat or rye component — the bread won't hold together. Expecting a light, airy crumb — broa is dense by design.
