Tips & Substitutions
For the best texture, ensure your egg whites are at room temperature before beating. If you want a different sweetness level, consider reducing the sugar slightly or using a sugar substitute. You can also swap white Karo syrup with light corn syrup if needed. This icing is versatile and can be flavored with different extracts such as almond or lemon for a unique twist.

Frequently Asked Questions
Can I use pasteurized egg whites instead of fresh?
Yes, pasteurized egg whites are a safe alternative and can be used in this recipe without compromising the texture. Just measure out the equivalent amount of liquid egg whites as specified for fresh eggs.
What can I do if the icing doesn’t hold its shape?
If your icing doesn't hold its shape, it may be due to overbeating or incorporating too much syrup too quickly. Ensure you beat until just glossy and peaks form, and try adding a little more powdered sugar to thicken it if necessary.
How can I make this icing more colorful?
To enhance the color of your icing, use gel food coloring instead of liquid, as it won't alter the consistency. Start with a small amount and gradually increase until you achieve your desired shade. This is especially fun for themed parties or special occasions.
