Tips for Royal Red Icing

trucolor red icingNatural red  colors derived from an Anthocyanin (berries and some vegetables) need an acidic medium, by replacing the suggested amount of water with lemon juice to dissolve the TruColor™ powder. The Citric Acid and Ascorbic Acid (vitamin C) in the lemon juice will lower the pH and help change the red color to a true red.  Without adding a wholesome food acid, you will only achieve a “berry” color which is nice but not the red you want for icing on a fire engine cake or cookie!

Royal Icing is hard to color, and you need to make sure that your TruColor™ powder is completely dissolved or you may see specs of undesolved color in your icing. Royal Icing is thick and foamy so it absorbs color easily and it often takes more of any type of color to get a dark shade.  Although it is possible to get very nice shades when blended “into” icing or dough it often can be more effective and less expensive to achieve brilliant hues and shades by painting on the surface of dry royal icing with an airbrush or a paint brush when using natural colors.

With any natural color it is always best to test and color a small amount in your icing to see the results first before committing to making a whole batch.

To make a brilliant natural red color you must have patience as you will need to continuously add a wholesome food acid and let the red color develop over a period of time. Natural red that is derived from certain berries and vegetables need an acid to bring out a true red hue.  Naturally occurring food acids include citric acid from citrus fruits, tartaric Acid or Potassium bitartrate is a byproduct of wine making (Cream of Tartar) and malic acid found in apples are referred to as wholesome acids, and is the reason that many natural fruits have that unique tart taste found in cranberries, grapes, berries, plums, cherries, oranges, lemons, guava, grapefruits, pineapples, apples, peaches and other fruits with seeds.

For an even deeper red appearance add an additional 1/4th teaspoon TruColor purple carrot dissolved in several drops of lemon juice.  Continue to add lemon juice and blend into your “thick” royal icing mixture until you thin the icing and reach a consistency where you can pipe it through a decorating bag.  Natural colors will deepen over time and your red color will also continue to develop and darken when it is stored and darken even more as the icing dries on you cookie.
