How do you stop fresh milk curdling?

1. Avoid sudden temperature changes: Sudden temperature changes can cause the proteins in milk to coagulate, leading to curdling. Make sure to store fresh milk in the refrigerator at a consistent temperature of around 40°F (4°C) and avoid leaving it out at room temperature for long periods of time.

2. Use fresh milk: Fresh milk is less likely to curdle than milk that has been sitting for a while. Check the expiration date on the milk carton and try to use it within a few days of purchase.

3. Scald the milk before adding it to acidic ingredients: If you are adding milk to an acidic recipe, such as a custard or pudding, it is important to scald the milk first. This means heating the milk over medium heat until it just starts to simmer. Do not let it boil, as this can also cause the milk to curdle.

4. Stir constantly when adding milk to hot liquids: When adding milk to a hot liquid, such as soup or sauce, it is important to stir constantly to prevent it from curdling. This will help distribute the heat evenly and prevent the proteins from coagulating.

5. Use a thickening agent: If you are concerned about the milk curdling, you can add a thickening agent such as cornstarch or flour. This will help bind the proteins in the milk and prevent them from coagulating.

6. Add a little salt: Adding a little salt to the milk can help prevent it from curdling. Salt can interact with the proteins in milk and help them stay dispersed.

7. Use a slow cooker: If you are making a dish that requires milk, such as oatmeal or rice pudding, you can use a slow cooker to help prevent the milk from curdling. The slow cooker will heat the milk gently and evenly, reducing the chances of it curdling.

8. Use low-fat milk: Low-fat milk is less likely to curdle than whole milk because it contains less protein. If you are concerned about the milk curdling, you can use low-fat milk or even skim milk.

By following these tips, you can help prevent fresh milk from curdling and ensure that your dishes turn out perfectly.
