Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 3% of all ingredient pairs, and 35,031 recipes mention both. Both carry beta-damascenone, which smells apple, rose. The science ↓
The recipe
Ingredients
Directions
Prepare the chestnut base
Boil the chestnuts in water until tender, then peel and press through a fine sieve.
Dissolve isinglass in ½ cup of new milk.
Mix the chestnut puree with ¾ cup of rich unboiled cream gradually.
Flavor and set
Add the dissolved isinglass, bruised bitter almonds, and thinly cut lemon rind.
Stir in dried cherries and candied citron.
Press the mixture into a mold greased with a little salad oil.
Refrigerate for a few hours until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chestnuts
- Cooked and pressed into a puree, they form the thick body of the cream.
- Isinglass
- A gelatin-like setting agent that firms the cream as it chills.
- Rich unboiled cream
- Adds fat for a smooth, rich texture and mellows the chestnut flavor.
- Dried cherries
- Add chewy texture and fruity sweetness throughout the set cream.
- Candied citron
- Adds sweet, chewy pieces and a candied citrus flavor.
The step that matters
Dissolving the isinglass. Isinglass must be fully dissolved before it is mixed in, or it will leave lumps and set unevenly. Once it cools and gels, it cannot be smoothed out, so the mixture should stay warm and well stirred while it is added.

Fit is the average pairing score against chestnut, sugar, cream, vanilla. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
