Bread Baking Basics: The Role of Every Ingredient in Pullman Loaves❗

🔆1. Flour

To bake great Pullman loaves, use bread flour with a protein content above 12.6%. Higher protein builds a stronger gluten network, which gives the dough both elasticity and extensibility. Besides protein content, check the ash content if it is listed on the bag. Ideally, look for a low ash content around 0.4%, which helps loaves rise tall with a fine, silky crumb. These are my personal takeaways from ten years of baking bread. You can find my detailed review of North American bread flours in my dedicated flour post.

🔆2. Liquid (Mainly Milk or Water)

Liquids serve two primary functions: first, hydrating the flour proteins so they bond into gluten; second, dissolving the dry ingredients so everything disperses evenly. We also frequently use icy cold liquid to keep dough temperature down, preventing premature fermentation in the mixer before reaching full windowpane, which would otherwise lead to a coarse, sponge-like crumb.

🔆3. Eggs

Egg whites boost the dough's elasticity and extensibility. Egg yolks add rich color, sheen, and tenderness (thanks to their natural lecithin), keeping the baked loaf soft and pillowy. Using half to one whole egg in a single 450g loaf hits the sweet spot.

🔆4. Yeast

Yeast drives fermentation, producing gas that makes the dough rise. The standard baseline ratio is 5g of instant dry yeast per 500g of flour (1%).

🔆5. Salt

Salt plays two essential roles: it regulates yeast activity so fermentation doesn't run away too fast, and it strengthens the gluten network. Never skip the salt, even when baking sweet breads.

🔆6. Sugar

First, sugar feeds the yeast to support steady fermentation.

Second, sugar is hygroscopic, helping the crumb retain moisture.

Third, sugar acts as a natural preservative to slow spoilage.

Fourth, sugar promotes caramelization and golden crust browning.

🔆7. Butter

Butter tenderizes the crumb, enriches the flavor and mouthfeel, and slows down staling (retrogradation).

🔆8. Dairy Products

Yogurt, cream cheese, heavy whipping cream, sour cream, sweetened condensed milk, and baking milk powder all deepen milky aroma, improve crumb softness, and keep the bread fresh longer.
