Ingredients

  • 2 cups sugar
  • 1/2 cup water
  • 1 tablespoon vinegar
  • 2 egg whites
  • 1 teaspoon vanilla

Instructions

  1. Let sugar, water, and vinegar cook to soft ball stage.
  2. Pour half of the syrup slowly over stiffly beaten egg whites.
  3. Continue beating the mixture.
  4. Return the remaining half of the syrup to the stove and cook until hard ball stage.
  5. Pour the hot syrup slowly over the egg whites, beating continuously until the mixture reaches proper thickness to spread.

Tips & Substitutions

To achieve the perfect consistency, ensure your egg whites are at room temperature before beating them to stiff peaks. If you don't have vinegar, lemon juice can be a suitable substitute to help stabilize the egg whites. For a flavor twist, consider adding a pinch of salt or using flavored extracts in addition to vanilla. Keep a candy thermometer handy for accurate temperature readings during cooking.

Serving Suggestions

This boiled icing is ideal for topping cakes, cupcakes, or pies, adding a glossy and sweet finish. It pairs beautifully with American recipes like Mrs. Upson's Blueberry Muffins or even as a filling for chocolate desserts. Consider using it to frost a layer cake or as a dip for fruit, adding a delightful sweetness to your dessert spread.

Storage & Reheating

Boiled icing is best used immediately, but if you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To revive the icing, gently rebeat with a mixer until fluffy again, but be mindful that it may not hold its shape as well after refrigeration.

Frequently Asked Questions

Can I make boiled icing ahead of time?

Boiled icing is best when fresh, as it can lose its texture over time. However, you can prepare the syrup in advance and store it separately. When ready to use, reheat the syrup gently and then combine it with whipped egg whites.

What can I do if my icing is too runny?

If your boiled icing is too runny, it may not have reached the right temperature during cooking. You can try reheating it slightly and beating it again to help thicken it, but be cautious to avoid cooking the egg whites too much.

Is it safe to eat the egg whites in boiled icing?

Yes, the egg whites in boiled icing are cooked by the hot syrup, which helps eliminate safety concerns. However, if you're concerned about raw egg consumption, consider using pasteurized egg whites for peace of mind.
