Can Vinegar Be Used to Make Yogurt?

Yes, kitchen acids like vinegar can indeed be used to curdle milk, which is a traditional method for creating a sour, yogurt-like base or homemade cheese starters.

To try this method, start by heating a small amount—about one-fourth cup—of milk for roughly two minutes. Mix in a bit of vinegar, tamarind, or even green chili stalks, along with a small pinch of salt. Cover the container securely with a lid and let it sit undisturbed for 10 to 12 hours until the mixture develops a distinct sour profile.

Once this sour starter is ready, you can use it to help process a larger batch—such as heating 500 milliliters of fresh milk—to complete your yogurt-making process. Keep in mind that while this method successfully sours milk, the texture and flavor will differ slightly from traditional yogurt cultured with live probiotic bacteria.
