Ingredients

  • 2 egg whites
  • 2 1/4 cups brown sugar
  • 5 teaspoons water
  • 1/2 teaspoon vanilla

Instructions

  1. Combine egg whites, brown sugar, and water in the top of a double boiler.
  2. Beat well to mix.
  3. Place over rapidly boiling water and beat constantly until mixture stands in peaks (about 7 minutes).
  4. Remove from heat.
  5. Add vanilla.
  6. Beat until the icing reaches the right consistency.

Tips & Substitutions

For best results, use fresh egg whites at room temperature, as they whip better. If you're looking for a lower sugar option, consider reducing the brown sugar slightly or using a sugar substitute that measures similarly. Beating the mixture constantly over boiling water is crucial to achieving the right consistency; this is where the magic happens. If you prefer a different flavor, try adding almond extract instead of vanilla.

Serving Suggestions

This seafoam icing is delightful when used to top cakes or cupcakes, especially light cakes like Japanese Mandarin Orange Cake. It also pairs wonderfully with desserts like Angel Wings (Polish)(Chrusciki) for a textural contrast. For a festive touch, consider using it to frost cookies or as a filling for pastries. Serve with a side of fresh fruit to balance the sweetness.

Storage & Reheating

Store any leftover seafoam icing in an airtight container in the refrigerator for up to three days. If the icing thickens, you can gently rewhip it to restore its texture. Avoid freezing, as the icing may separate and lose its airy consistency upon thawing. Always keep it covered to maintain freshness.

Frequently Asked Questions

Can I use pasteurized egg whites instead of fresh?

Yes, you can use pasteurized egg whites as a safer alternative, especially if you're concerned about raw eggs. They whip well and will still give you a nice consistency in your seafoam icing. Just ensure that they are at room temperature for optimal results.

How can I tell when the icing is ready?

The icing is ready when it holds stiff peaks, meaning that when you lift the whisk or beaters, the icing stands upright without drooping. This usually takes about 7 minutes of constant beating over boiling water. If it appears glossy and thick, you’re on the right track.

What can I do if my icing is too runny?

If your icing is too runny, it may need more beating. Continue to beat it over the heat until it thickens and forms stiff peaks. Alternatively, you could add a bit more powdered sugar to help thicken it, but this may alter the flavor slightly.
