Red Seal Baker Practice Exam 2026 – Comprehensive Prep Guide

Introducing steam during the baking of bread is a critical technique that serves multiple purposes, with a key focus on creating a crusty exterior and promoting rapid expansion. When steam is injected into the oven, it increases the humidity and allows the outer layer of the dough to remain moist during the initial stages of baking. This moist environment prevents the crust from forming too quickly, which is essential for allowing the bread to expand fully and rise properly.

The heat from the oven causes the water in the steam to evaporate, leading to the formation of a crispy crust as the outer layer of the bread dries out during the baking process. The steam also aids in gelatinizing the starches on the bread’s surface, contributing to the Maillard reaction, which enhances browning, flavor, and appearance.

In contrast, while improving flavor is an important aspect of baking, steam's primary role is not directly related to flavor enhancement. It also does not cool the bread or prevent burning; instead, it is specifically beneficial for texture and crust development. Understanding this process is essential for successful bread baking and achieving the desired qualities in the finished product.
