“Eierstich”, or royale, is popular clear soup garnish in Germany. Royale is an egg custard, baked in a water bath and then cut into a diamond shape or other more fancy shapes. This recipe for royale has a few pointers which will guarantee success. Royale is often used in “Hochzeitssuppe”
Eierstich mit Sahne in der Mikrowelle, German Recipe for the microwave.
1/2 cup milk (or cream)
2 egg yolks
Freshly grated nutmeg to taste
1/4 tsp. salt
You need two baking pans to bake the royale. You will make a water bath (bain marie) for the royale custard. One can be a heatproof teacup or a ramekin which fits inside the second pan. The second, larger pan will hold hot water for baking the custard so it does not curdle.
Heat oven to 300°F. Boil several cups of water for the water bath.
Generously butter the form you’re using (can be a teacup, a ramekin or a small casserole dish), line with a piece of wax paper cut to fit the bottom and butter that, too.
Heat the milk or cream in a small pan to just below the boiling point.
Beat the egg, egg yolks, nutmeg, and salt together. While whisking constantly, pour the hot milk in a thin stream into the eggs.
Let the foam, if any, settle. Pour through a fine sieve into your form. The sieve collects any cooked egg and pieces of large nutmeg. Try not to let the foam flow on top as it forms a disagreeable crust which you must remove after baking.
Place the larger dish in the oven, then your custard dish inside. Pour hot water around the outside about 2/3 of the way up the form.
Bake for 20 to 30 minutes (depends on how thick your royale is) or until set.
Let the royale cool for 20 minutes or more (you may also refrigerate), then unmold onto a cutting surface by loosening the sides of the custard with a knife and then gently sliding or flipping the custard out of the form.
If you used a flat form, you can cut the royale immediately into fancy shapes such as diamonds. You may also use a cookie cutter.
If you baked the royale in a teacup or smaller form, you must cut the custard into quarter or half inch layers with a knife and use the individual layers to cut fancy shapes.
You may color your “Eierstich” for fun (since it is used in clear soup) with a teaspoon of tomato paste for red or finely minced parsley for green. You may also use other fresh herbs, but filter through a sieve before baking because the pieces rise to the top of the “Eierstich.”
To serve, place several pieces in the bottom of a soup plate, pour hot broth over it and garnish with herbs as desired.
Serve at once.
Do not cook the royale in the broth because it cannot take much handling and the broth will become cloudy.
A good “Eierstich” is known for its smooth, velvety texture, which is a bit like soft tofu. If the water in the water bath comes to a boil in the oven the royale will become porous and if you beat air into it before it is baked the same thing could happen.
Other methods for cooking “Eierstich” include cooking it in a zip top plastic bag in a water bath, cooking it in simmering water on the stove top and cooking it in a double boiler method over the potato pan. None of these guarantee a smooth product but are less complicated.
The egg to yolk ratio usually cited is one extra yolk per egg. The more milk you add, the softer the royale (harder to handle). Some “Eierstich” recipes contain no milk or cream, or just a little. Experiment until it works for you.
