Making Sour Milk for Baking
Instead of waiting for milk to sour on its own, which can lead to spoilage, you can create a safe and effective sour milk substitute. This process uses an acid to curdle the milk slightly. This acidity is ideal for baking recipes that call for sour milk.
Ingredients and Steps
Here's a step-by-step guide, based on the provided reference, to sour milk using vinegar or lemon juice:
| Ingredient | Quantity | Purpose |
|---|---|---|
| Whole Milk | To reach 1 cup (250 ml) | Main liquid |
| White Vinegar or Lemon Juice | 1 tbsp (15 ml) | Acid to curdle the milk |
Instructions:
- Measure the Acid: In a liquid measuring cup, pour 1 tablespoon (15 ml) of either white vinegar or lemon juice.
- Add Milk: Fill the remaining portion of the measuring cup with whole milk until you reach a total of 1 cup (250 ml).
- Stir Gently: Stir the milk and the acid together.
- Let it Stand: Let the mixture sit for 5 minutes. This allows the milk to curdle slightly.
- Ready to Use: The mixture should appear slightly thicker and is now ready to use in your recipe.
Important Notes
- The key is to achieve the right acidity level by using vinegar or lemon juice.
- Do not use naturally soured milk, as it is spoiled.
- This method is tailored for baking applications.
By following these steps, you'll have a safe and reliable sour milk substitute.
