The recipe makes about a quart, which is a bit too much for us, so I usually put some in a pretty jar and pass it on to a friend or neighbor.
A couple of helpful tips: 1. If you don't have buttermilk, you can use 1 c. milk and 1 Tbsp. white vinegar or lemon juice and let it sit for 5-10 minutes. 2. If you don't have mayo, you can substitute sour cream or greek yogurt. Do NOT use Miracle Whip.
