Step 1

In a glass bowl, combine the dry ingredients.   Add 2T water.   Mix well.   Add more water as necessary to reach a very thick consistency.   When you drag a knife through it, you want to see a clean path left.

Step 3

If it’s too thick, add a tiny amount of water, mix, and pull your knife through again.

Step 5

If it’s too runny, add more sugar.

Step 7

Put icing into a zip-seal baggie & cut off a corner.   I found a slightly large hole worked best (my icing came out about as thick as a squirt of toothpaste).
