Directions
Preparing the Frosting
- Set Up a Double Boiler: Fill a medium saucepan with about 2 inches of water and bring it to a simmer. Place a heatproof bowl over the saucepan, making sure the bottom of the bowl does not touch the water.
- Combine Ingredients: In the heatproof bowl, combine the egg whites, granulated sugar, cold water, light corn syrup (or cream of tartar), and a pinch of salt.
- Whisk Constantly: Using a handheld electric mixer or a whisk, beat the mixture constantly over the simmering water. This process should take about 5-7 minutes. The frosting is ready when it holds stiff peaks and has a glossy, marshmallow-like texture.
- Remove from Heat: Once the frosting has reached the desired consistency, remove the bowl from the heat.
- Add Vanilla: Stir in the pure vanilla extract and continue to beat for another minute to fully incorporate the flavor.
Kitchen Equipment Needed
- Medium saucepan
- Heatproof bowl
- Handheld electric mixer or whisk
- Measuring cups and spoons
- Spatula
Tips for Perfect 7 Minute Frosting
- Consistent Whisking: Make sure to whisk constantly while the mixture is over the simmering water to ensure the sugar fully dissolves and the egg whites cook evenly.
- Stiff Peaks: The frosting should hold stiff peaks when it’s ready. This means that when you lift the whisk or beaters, the frosting should stand up firmly without collapsing.
- Avoid Overheating: Be careful not to let the water in the saucepan boil vigorously. A gentle simmer is ideal to prevent the frosting from overheating and becoming grainy.
Storing Leftovers
This frosting is best used immediately, but you can store any leftovers in an airtight container at room temperature for up to 2 days. Avoid refrigerating, as the frosting can become sticky and lose its texture.
Recipe Variations and Swaps
- Chocolate Version: For a chocolate variation, sift in 2-3 tablespoons of unsweetened cocoa powder during the final mixing stage.
- Citrus Twist: Add a teaspoon of lemon or orange zest along with the vanilla extract for a citrus-flavored frosting.
- Almond Flavor: Substitute the vanilla extract with almond extract for a nutty twist.
