When it comes to baking, there are many techniques and ingredients that can make or break the final product. One such technique that has been used for centuries is scalding milk. But what is the purpose of scalded milk, and how does it impact the final product? In this article, we’ll delve into the world of scalded milk and explore its importance in baking.
What is Scalded Milk?
Scalded milk is milk that has been heated to a temperature of around 180°F to 190°F (82°C to 88°C), just below the boiling point. This process is also known as “tempering” the milk. Scalding milk serves several purposes, including:
- Killing bacteria and extending shelf life: Scalding milk kills any bacteria that may be present, making it safer to consume and extending its shelf life.
- Changing the protein structure: Scalding milk denatures the proteins, making them more accessible to enzymes and improving the overall texture of the final product.
- Improving emulsification: Scalding milk helps to create a more stable emulsion, which is essential for baked goods like cakes, custards, and sauces.
The Science Behind Scalded Milk
To understand the purpose of scalded milk, it’s essential to look at the science behind it. Milk is composed of several components, including proteins, fats, carbohydrates, and minerals. When milk is heated, these components undergo significant changes.
Denaturation of Proteins
Proteins are an essential component of milk, and they play a crucial role in determining the texture and structure of baked goods. When milk is heated, the proteins denature, or unwind, and reorganize into a more stable structure. This process is known as denaturation.
Denaturation of proteins is essential for creating a smooth and even texture in baked goods. When proteins are denatured, they become more accessible to enzymes, which helps to break down the proteins and create a more stable structure.
Emulsification
Emulsification is the process of combining two or more liquids that don’t normally mix, like oil and water. Milk is an emulsion of fat and water, and scalding milk helps to create a more stable emulsion.
When milk is heated, the fat molecules become more dispersed, creating a more stable emulsion. This is essential for baked goods like cakes, custards, and sauces, where a smooth and even texture is crucial.

What is scalded milk and how is it made?
Scalded milk is milk that has been heated to a high temperature, typically around 180°F to 190°F (82°C to 88°C), to create a specific reaction that changes its composition. To make scalded milk, you simply heat milk in a saucepan over medium heat, stirring occasionally, until it reaches the desired temperature.
The scalding process involves heating the milk to a point where the casein proteins are denatured, and the whey proteins are coagulated. This process creates a smooth, creamy texture and a slightly sweet flavor. Scalded milk can be made with whole, low-fat, or nonfat milk, and it’s a simple process that requires minimal equipment.
What is the purpose of scalding milk in baked goods?
Scalding milk serves several purposes in baked goods. Firstly, it helps to create a tender crumb and a smooth texture. The denatured proteins in scalded milk help to strengthen the gluten network in the dough, resulting in a more even texture. Secondly, scalded milk adds flavor to baked goods, with a slightly sweet and nutty taste that enhances the overall flavor profile.
Scalded milk also helps to improve the browning of baked goods. The Maillard reaction, a chemical reaction between amino acids and reducing sugars, occurs when scalded milk is combined with sugar and heat. This reaction creates new flavor compounds and browns the surface of the baked goods, giving them a golden-brown color and a crispy texture.
How does scalded milk affect the texture of baked goods?
Scalded milk has a significant impact on the texture of baked goods. The denatured proteins in scalded milk help to create a tender crumb and a smooth texture. The casein proteins, which are normally responsible for creating a tough, chewy texture, are denatured during the scalding process, resulting in a more even texture.
The scalding process also helps to reduce the amount of liquid in the dough, resulting in a more tender crumb. When scalded milk is combined with flour, it helps to create a stronger gluten network, which gives baked goods their structure and texture. This results in a more even texture and a better crumb structure.
Can I use scalded milk in place of regular milk in recipes?
Yes, you can use scalded milk in place of regular milk in most recipes. However, keep in mind that scalded milk has a stronger flavor and a thicker consistency than regular milk. You may need to adjust the amount of liquid in the recipe and the cooking time to get the best results.
When substituting scalded milk for regular milk, start by using a 1:1 ratio and adjust as needed.
