Description
A heat-stabilized foam of egg whites and sugar with superior structural integrity.
Technical
Egg white proteins (ovalbumin, ovotransferrin) partially denature at 60-65°C during bain-marie heating, while sucrose dissolves completely into syrup. Subsequent mechanical agitation aligns proteins into a stable network that traps sugar syrup droplets, creating a glossy, dense foam resistant to weeping.
Culinary Significance
Provides the sturdiest meringue base for piping intricate designs, with a satiny texture ideal for buttercream incorporation. Less prone to collapse than French meringue but more pliable than Italian.
