Sour cream container sizes in cups
Sour cream is sold by weight, so the tub rarely matches the cups a recipe asks for. At about 240g per cup, an 8 oz (227g) container is just shy of 1 cup, a 16 oz (454g) tub is about 1⅞ cups, and a 24 oz tub is about 2¾ cups.
Out of sour cream? Plain full-fat Greek yogurt is the closest swap — 1:1 by volume, with a similar tang and the same approximate weight per cup. It works in dips, baking and as a topping, though it is a little thinner straight from the tub.
