Combine all of the ingredients in a medium-sized bowl. I use a rubber
spatula or sturdy fork to avoid clumps. Mix until smooth and thick.
If the frosting is too thick then thin it by adding 1/4-teaspoon of
water at a time, until it's the consistency your prefer.
Notes
This frosting is easy to prepare and has a pleasant tangy flavor. If
you prefer your frosting to be tarter then use 1-1/2 tablespoons of
both vinegar and water.
I feel this frosting is best on spicy cakes like gingerbread, carrot
cake, cinnamon cake, spice cake, apple-spice cake etc. It makes an
interesting contrast to chocolate cake and might be worth trying if
you like unusual combinations. Makes enough to frost the top of an 8
or 9-inch cake. Double the recipe to have enough for a layer cake.
And above
all things have fervent charity among yourselves: for charity shall
cover the multitude of sins. Use hospitality one to another
without grudging. As every man hath received the gift, even so
minister the same one to another, as good stewards of the manifold
grace of God.--1 Peter 4:8-10
