Ingredients
Directions
Prepare the mold
Trim the savoy biscuits to fit closely in a plain mold, lining the bottom and sides.
Make the custard
In a saucepan, combine ratafias, sugar, orange rind, lemon rind, cinnamon, maraschino, 1 pint of cream, and beaten egg yolks.
Stir the mixture over low heat for a few minutes, then strain it.
Add the whipped cream and dissolved isinglass, mixing well.
Set and chill
Set the mixture in a basin filled with rough ice until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the cream mixture as they set gently over low heat, adding richness.
- Isinglass
- Gelatinizes the mixture so it sets firmly enough to hold its shape when turned out.
- Savoy biscuits
- Form the crisp, absorbent lining that holds the set cream in the mold.
- Cream
- Adds fat and smooth body, giving the set dessert a rich, soft texture.
- Whipped cream
- Lightens the custard with air, making it softer and less dense.
- Sugar
- Sweetens the mixture and balances the flavor of the citrus and liqueur.
The step that matters
Stir the mixture over low heat for a few minutes, then strain it.. Egg yolks thicken and can scramble if overheated, so gentle low heat and constant stirring keep the custard smooth. Straining removes any cooked bits or rind.
