Straus Organic Plain Greek Yogurt ($8)
My roommate and I go through one of these giant containers of yogurt a week, at least. It's rich, ultra-thick, and hardly needing adornment. My favorite way to eat it is like dessert with marshmallows, raspberries, and chocolate shavings. It's also great used instead of sour cream in baked potatoes or in lieu of crème fraiche in Gordon Ramsay's scrambled eggs recipe.
