Baking Science: The Wonderful Effects Of Milk In Baking (2024)

Milk is such a common ingredient in baking; you wouldn’t even bat an eyelid to see a recipe that includes it. But have you ever wondered what milk actually does in baked goods? Before you think of skipping the milk, using milk alternatives or non-dairy options, it’s important to understand what makes milk crucial to the recipe.

After all, an excellent baker should possess good knowledge of the science behind baking, such as the different types of flour and when to use them. If you’re ready to get schooled, here’s what milk is doing when you use it in your bakes.

Adds moisture

The balance of dry and wet ingredients is a fundamental concept that every baker should know. Along with water, butter, and eggs, milk is one of those ingredients that adds the required moisture for the batter to form.

In recipes which call for milk, you can easily add splashes of milk to soften the mixture if you find the batter too dry or stiff.

Activates the ingredients

Besides simply adding liquid content to the batter, milk plays a crucial role in activating key ingredients in baking. Milk is a solvent for sugar, and the proteins contained in milk add structure and firmness to muffins and cupcakes.

Milk also activates gluten, triggering the wonderful chemical reactions that make bread soft and fluffy. When using milk for baking soft bread, you should warm up the milk first before use.

Adds sweetness

Thanks to naturally occurring fats and sugar, milk is helpful in adding a light sweetness and rich, full-bodied taste to your baked goods. Of course, the amount of fat also depends on the type of milk you use. Skimmed milk will result in a thinner batter and a flavour that is less rich. Some recipes will only work with certain types of milk – look out for the right type before reaching for the dairy shelf.

Aids browning

Milk plays a role in adding a touch of golden glow to your bakes. It may not be quite as shiny or glossy as an egg wash, but enough to impart some structure and a slight crunch to the outer layer. The browning effect is actually the same as caramelising sugar, and this is due to the sugar content in milk. So, the next time you wonder how your favourite online bakery in Singapore does that beautiful brown crust, now you know!

With the newfound knowledge of what milk does for your baking recipes, you are better equipped to decide if you should continue using it in your baking or omit it for other alternatives.
