Ingredients

  • 1 cup white Karo syrup
  • dash of salt
  • 2 egg whites
  • 1/2 teaspoon vanilla
  • food coloring (optional)

Instructions

  1. In a saucepan, bring the Karo syrup to a rolling boil for 1 minute.
  2. Beat the egg whites and a dash of salt until stiff peaks form.
  3. Pour the hot syrup over the beaten egg whites and continue beating until the mixture forms peaks.
  4. Add vanilla and a few drops of food coloring if desired.
  5. Use to ice a large layer cake.

Tips & Substitutions

To achieve the best texture, ensure your egg whites are at room temperature before beating. If you don't have white Karo syrup, light corn syrup can be used as a substitute. For a different flavor, you might experiment with almond extract instead of vanilla. Make sure to beat the syrup into the egg whites gradually to avoid cooking the eggs too quickly.

Serving Suggestions

This sugar-free icing is perfect for decorating a large layer cake, providing a glossy finish that pairs beautifully with light cake flavors like vanilla or lemon. Consider serving it alongside Cam'S Fruit Pancakes for a sweet brunch treat. Alternatively, it can be used to top cookies or cupcakes for festive occasions.

Storage & Reheating

This icing is best used immediately, but if you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Before using, allow it to come to room temperature and re-whip lightly to restore its texture. Avoid freezing, as it may separate upon thawing.

Frequently Asked Questions

Can I use this icing for piping decorations?

Yes, this icing can be piped, but it may be best for larger decorations due to its texture. For finer work, consider adding a bit more powdered egg white to thicken it. If you're looking for intricate designs, using a different frosting type might yield better results.

How can I adjust the sweetness if I want it sweeter?

Since this icing is sugar-free, it's naturally less sweet than traditional frostings. If you want to increase the sweetness, consider adding a sugar substitute like stevia or erythritol. Start with a small amount and adjust to taste, keeping in mind that some substitutes may alter the texture.

What can I do if the icing is too runny?

If your icing turns out too runny, it's likely due to insufficient beating or not enough syrup. Try beating it longer until it thickens. If that doesn't help, adding a bit more powdered egg white can help achieve the desired consistency without compromising the flavor.
