Instructions
- Put the egg whites, sugar, corn syrup, and salt in a large heatproof bowl set over a pan of simmering water.
- Beat with a hand mixer on high speed until the frosting holds stiff, glossy peaks and reaches 160°F, about 7 minutes.
- Remove from the heat, add the vanilla, and beat 1 minute more.
- Use right away; it sets a light crust as it stands.
Tips
- Vanilla swap: use vanilla bean paste 1:1 in place of the extract for visible specks, or the seeds of 1 vanilla bean for each tablespoon of extract.
- Best vanilla for this: Madagascar (rich, creamy, classic), or Mexican (spiced, warm, woodsy). Any pure vanilla works.
- Storage: Best the day it's made. Keep frosted cakes covered at room temperature and serve within 1 day.
