Cooking with yogurt is common in Lebanon. In those dishes, yogurt is the base sauce as opposed to just an ingredient in a sauce. While I am not good at mastering yogurt sauces, I know that this involves adding mashed garlic, chopped cilantro (or mint) and salt and boiled till it thickens (you may need the help of corn starch).
A few dishes are cooked in yogurt sauce. Most popular are Kebbeh (see November 4 entry - Pumpkin Kebbeh) or Mehshi (stuffed zuchinni) (see August 20 entry - Sheikh el Mehshi).
Tonight's yogurt cat opted for mini zucchinis stuffed with rice and meat.
Thank you Susan.
