Using gel food coloring in royal icing is a straightforward process that allows you to achieve vibrant and consistent colors for your decorated treats. Here's a breakdown of how to do it effectively:
Steps for Coloring Royal Icing with Gel Food Coloring
-
Start with White Royal Icing: Ensure your royal icing is a bright white, as this will act as the base for your colors. Any off-white tint will affect the final color.
-
Use High-Quality Gel Food Coloring: Gel food colors are concentrated and won't change the consistency of your icing as much as liquid food coloring. Brands like AmeriColor, Wilton, and Chefmaster are popular choices.
-
Add Color Gradually: This is the key to achieving your desired shade. Start with a very small amount of gel color (a drop or two) using a toothpick or the end of a small spoon.
-
Mix Thoroughly: Use a spatula or mixer to fully incorporate the color into the icing. Make sure there are no streaks of color remaining.
-
Assess and Adjust: Check the color intensity. If it's not dark enough, add another small amount of gel color and mix again. Repeat until you achieve the desired shade. Remember that the color will deepen slightly as it sits.
-
"Color Bloom" Consideration: Darker colors, especially red and black, often benefit from a "color bloom" period. After mixing, cover the icing and let it sit at room temperature for 2-4 hours (or even overnight in the refrigerator). This allows the color to fully develop and deepen, potentially saving you from using excessive amounts of gel color.
Tips for Specific Colors
-
Red and Black: These colors are notoriously difficult to achieve without using a lot of food coloring. Add the gel color gradually, mixing well after each addition, until the icing is close to the desired color. Then, allow it to sit for the color bloom. This method prevents the icing from becoming too liquid or having a bitter taste from too much dye.
-
Pastel Colors: Use a very small amount of gel food coloring. It's much easier to add more color than to try and lighten a color that's too dark.
Troubleshooting
-
Icing is Too Thin: If you accidentally add too much gel color (and therefore too much liquid), thicken the icing by adding a small amount of powdered sugar (1/2 teaspoon at a time), mixing well after each addition.
-
Uneven Color: Make sure you are mixing the gel color in completely. Streaks of color indicate that the icing isn't properly mixed.
-
Bitter Taste: Using too much gel food coloring, especially with red or black, can result in a bitter taste. Using the color bloom technique can help minimize this.
By following these steps and tips, you can effectively use gel food coloring to create beautiful and vibrant royal icing for your decorating projects.
