Cooking with Yogurt

Marinades

Yogurt tenderizes meat for kebabs:

  • Acidic environment breaks down proteins
  • Keeps meat moist during grilling
  • Adds subtle tang

In Stews

Sometimes stirred into stews at the end:

  • Adds creaminess
  • Must be tempered to prevent curdling
  • Creates slight tanginess
