Ethereal Orange Sabayon

Inspired by citrus, I made an ethereal dessert: orange sabayon with satsuma mandarin sections and sliced almonds. It was light, flavorful, and a beautiful contrast to the sharpness of the mandarins.

Sabayon is a relative of the classic Italian zabaglione, which is a light, foamy dessert made with sweet Marsala wine, egg yolks, and sugar. It can be eaten on its own, used as a sauce, or frozen to become a semifreddo. The word “zabaglione” is derived from the Neapolitan dialect word “zapillare”, which means to foam (ref: Larousse Gastronomique).

For versions made without Marsala wine, the French term “sabayon” is typically used. The marvelous—but apparently out of print—Stars Desserts by Emily Luchetti has recipes for Champagne sabayon, cider sabayon (apple juice and calvados), Grand Marnier sabayon, and Basque sabayon (armagnac, orange flower water, dark rum and anisette).

Winter is citrus time and I had some delicious satsuma mandarin oranges and also some Cointreau in my pantry. Cointreau is a liqueur made from a blend of peels from bitter and sweet oranges. It was created in 1849 by confectioner Adolphe Cointreau and his brother in Angers, France. With these ingredients on hand, I slightly adapted on a recipe from Epicurious, with satsuma mandarin orange replacing the blood orange.

The first step was to combine the starting ingredients: two egg yolks, some sugar, orange juice, orange liqueur, and orange zest. Next, I whisked them together. The volume at this point was less than 1/2 cup, and climbed barely two centimeters up the side of the bowl.

Whisking the ingredients

After combining the ingredients, I put the bowl over a pan of simmering water and started cooking it, all the while whisking vigorously.

Over the period of a few minutes, a marvelous transformation occurred in the workbowl: a light foam formed and the mixture increased in volume by 4 or 5 times. I whisked until the foam reached 140 degrees F, then whisked for a few more minutes until it thickened so that the whisk left trails in the foam. At that time, I took it off the heat, let it sit for a few minutes, then spooned it over orange sections and topped with sliced toasted almonds.

Almost done

So how did the liquid in the second photo turn into the light foam in the last photo? The secret is to defeat surface tension. A foam is a collection of gas bubbles spread through a liquid or solid. Liquid-based foams like zabaglione are mostly water, and depend on the substances dissolved in the water to stabilize the foam. Pure water, as we all know, makes lousy bubbles. The reason for this is that the surface tension in the water and gravity pull apart any structure that you try to build. But when something like egg yolks and sugar are dissolved in—or emulsified with—the water, a temporarily stable matrix can be created. Egg whites, of course, make outstanding foams (as illustrated recently in IMBB #20, Has My Blog Fallen), primarily because of their albumen proteins. Egg yolks have significant fat content which interferes with foam formation. Nonetheless, with proper technique a light and foamy dessert can be whisked up.

  1. Wow! This dessert looks and sounds lovely. I think I’ll give it a try for Christmas. Very nice place you have here. I really enjoy the education I get from reading your posts. Thanks for sharing, Marc! :o)

  2. Glad you found something to make with all the lovely tangerines around…sans Indian spices (although a nice dusting of cardamom sounds like it might be tasty in that sabayon?!) Happy Holidays!
