The Custard Tradition: French, German, and Ermine
For those who prefer a less sugary, more “food-forward” frosting, the custard-based options are unparalleled. French Buttercream uses egg yolks instead of whites, resulting in a rich, yellow hue and a taste reminiscent of melted vanilla ice cream. It is incredibly decadent and best used for filling macarons or layering rich chocolate cakes. German Buttercream is essentially a “mousseline,” made by whipping butter into pastry cream. It is light, creamy, and far less sweet than American varieties.
Ermine Frosting, often called “Boiled Flour Frosting,” is a fascinating piece of culinary history. Before cream cheese frosting became the standard for Red Velvet cake, Ermine was the traditional topping. It involves cooking flour, milk, and sugar into a thick paste (a roux) and then whipping it into butter. The result is a texture as light as whipped cream but with the stability of a buttercream.
Stability and Storage
The enemy of frosting is heat. While Italian and American buttercreams are the most heat-resistant, Whipped Cream and Cream Cheese frostings must be refrigerated. When working with meringue buttercreams, remember that they can “break” or look curdled if the butter and meringue are at different temperatures. If this happens, don’t panic! Simply keep whipping, or slightly warm the bowl, and the emulsion will eventually come back together into a smooth, silky dream.
