Powdered sugar-water icing is nothing more than just that. I normally use a large stainless steel bowl and a hand whisk to make my icing in large quantity. Begin by putting 8-ounces of warm water in the bowl and begin adding powdered sugar while whisking until you achieve a very thick mass (too thick to use the whisk, so now it’s time to change over to a strong metal spoon to stir the icing. You know you have the right consistence when you lift the spoon from the icing and it forms a string.
You can add a small amount of salad oil (NOT OLIVE OIL), about 1-ounce per gallon of icing. If you add too much the icing will remain sticky instead of setting-up properly. Vanilla is also optional, since there is vanilla, artificial vanilla, and just about every strength (fold) of each that you can think of I can’t say how much to use but you don’t need very much, it’s not like the icing is going to have a great influence over the product, as long as it’s sweet tasting is all that your customers will be concerned about.
IMMEDIATELY after making the icing transfer it to plastic condiment bottles (you will need to cut the tip of each bottle to get the string size you want). No need to refrigerate, IF it should get too thick just place in a warm water bath and you’re good to go.
NEVER thin an icing with water, instead use a simple syrup to thin out any icing. To make a simple syrup just add 2-parts sugar and 1-part water to a pan, bring to a full boil (it will be clear, like water at that time), remove from heat, allow to cool for a short time ad add to any icing to thin it out. You can use this syrup just as it is after cooling too. BUT remember, if you over thin an icing it will look more like a donut glaze than an icing and it will set-up to a translucent color rather than white, additionally, over thinned icings may take longer than normal to set-up or they may remain sticky rather than setting-up dry.
Did your mother ever make an iced angel food cake at home? If she did she used a powdered sugar-water icing.
Making your own icing is as easy as boiling water but a lot safer.
Oh yes, one other thing, if your icing is lumpy after you’re finished making it DON’T try to mix the lumps out! Just take a break for 5-minutes or so, and stir once again and the lumps will be gone and the icing will be smooth.
