Azorean Sourdough Starter Recipe – A Taste of Portuguese Tradition from Oak Bluffs to New Bedford

If you’ve ever dreamed of baking authentic Portuguese sourdough bread, this Azorean Sourdough Starter Recipe connects you directly to over a century of culinary history. Passed down through generations, our heirloom starter traces its roots from São Miguel, Azores, to Oak Bluffs, Massachusetts, and finally to the heart of New Bedford, where it continues to rise—literally and culturally.

🌊 A Legacy of Portuguese Immigration and Breadmaking

Portuguese immigration to Oak Bluffs, MA, began in the late 18th and early 19th centuries. The first settlers were sailors and whalers from the Azores, bringing not only their skills but also their recipes and traditions.

By 1871, a New Bedford newspaper described the growing Portuguese presence as living in an “Eden-like city by the sea.” Among the many traditions carried across the Atlantic, sourdough bread stood out as a symbol of community, sustenance, and shared heritage.

Our 154-year-old sourdough starter has been lovingly maintained through generations, preserving the original culture brought from São Miguel. This heirloom starter delivers a distinctive depth of flavor—rich, tangy, and deeply aromatic—true to its Azorean roots.

💡 Pro Tip: Don’t Waste Your Discards!

Each time you discard your starter, save it in your refrigerator! Use it for:

Sourdough Portuguese Sweet Rolls or Sweet Bread: Recipes for adapting the classic Portuguese sweet bread (massa sovada) to include sourdough discard can be found online. The discard adds extra moisture and a mild tangy depth to the rich, buttery dough. TikTok users have shared specific techniques for making "Sourdough Discard Portuguese Sweet Rolls," including a version ready in an hour.

Malasadas: This is a type of Portuguese doughnut made from fermented dough. Bakers have shared recipes and tips for adapting traditional malasadas to use sourdough discard, which gives them a soft, tangy flavor. 

Sourdough Portuguese Buns (Papo Secos): Several bakers have adapted the recipe for these crusty, individual dinner rolls to use sourdough discard. The starter adds a complex flavor profile while producing a softer final product.

Sausage Bread (Pão com Chouriço): Portuguese sausage bread is traditionally baked with chourico. Some home bakers and enthusiasts have experimented with incorporating sourdough discard into the recipe to add flavor and a different texture to the dough. 

Bolo do caco: This traditional flatbread from the Portuguese island of Madeira is typically cooked on a tile or griddle.

Broa de milho (corn bread): Leavened with yeast, a sourdough discard can be added to broa for a tangier, more complex flavor. The discard adds character to this hearty bread, made from a mixture of cornmeal and rye or wheat flour. 

General uses in cooking:
Beyond specific Portuguese recipes, sourdough discard can be used in a variety of other culinary applications that align with cooking techniques found in Portuguese homes: 
Thickening sauces: Sourdough discard can be used as a thickener in sauces and gravies, much like flour or cornstarch. This adds a subtle tang and reduces food waste.
Fish or chicken batter: Adding sourdough discard to a batter for frying or pan-frying fish or chicken is a great way to add flavor and use up excess starter.
Baked goods: Discard can be used to make a variety of sweet and savory recipes, including muffins, crackers, brownies, and cookies. 

Or start another batch of Azorean starter with the discard at the same fermentation stage

This way, every part of your sourdough tradition continues to grow.
