Crème de Marrons – Homemade French Chestnut Cream
Ingredients
- 500 g 17.6 oz cooked, peeled chestnuts, weighed after puréeing
- 400 g 14.1 oz granulated sugar
- 100 ml about ⅓ cup + 1 tbsp water
- 1 vanilla bean or 1 tsp vanilla extract
- **Optional instead of vanilla:**
- 1 tbsp dark rum
Method
- If using fresh chestnuts, carefully score the shells with a sharp knife. Remove the hard outer shells and cook the chestnuts in plenty of water for approximately 20–25 minutes, until completely tender. Remove the thin brown inner skins while the chestnuts are still warm. If using already cooked and peeled chestnuts, skip this preparation.
- Drain the cooked chestnuts. Purée them using a food mill or food processor until as smooth as possible. Press the purée through a fine sieve to remove any coarse pieces. Weigh out 500 g (17.6 oz) of chestnut purée.
- Place the sugar and water in a heavy-bottomed saucepan. Heat gently until the sugar dissolves, then bring the syrup to a boil. Cook until it reaches approximately 112–116°C (234–241°F), known as the soft-ball stage. Avoid stirring continuously while the syrup boils, as this may encourage crystallization.
- Remove the saucepan briefly from the heat. Carefully add the chestnut purée to the hot sugar syrup in batches, stirring with a sturdy wooden spatula until well combined. The mixture may become quite thick at first.
- Return the saucepan to low heat. Add the seeds from the vanilla bean or the vanilla extract. Cook gently for approximately 15–20 minutes, stirring almost continuously and scraping the bottom and sides of the pan. The cream is ready when it is smooth, cohesive, and has the consistency of soft mashed potatoes. It does not need to become translucent.
- Spoon a little chestnut cream onto a cold plate and allow it to cool briefly. It should remain soft and spreadable without running like a thin sauce. If it is too runny, continue cooking gently for a few more minutes. If it is too thick, carefully stir in a little hot water.
- If using dark rum instead of vanilla, stir it into the chestnut cream at the end of cooking and mix well.
- Spoon the warm chestnut cream into clean glass jars. Close the jars, allow them to cool briefly, and refrigerate promptly. This recipe is not intended for storage at room temperature. Filling jars while the cream is hot does not make it shelf-stable.
Notes
Choosing chestnuts: Use sweet, edible chestnuts, not horse chestnuts. Vacuum-packed, unsweetened, pre-cooked chestnuts are a convenient alternative to fresh chestnuts.
For a smooth texture: A food mill produces an even chestnut purée. A food processor also works, but avoid processing for longer than necessary.
The cream thickens as it cools: Do not reduce it too far. A mixture that seems slightly soft while warm can become considerably firmer after refrigeration.
Vanilla or rum: Vanilla gives the most classic flavor. For a dessert variation, replace it with 1 tablespoon of dark rum, added near the end of cooking.
Sugar: The recipe uses 400 g of sugar for 500 g of chestnut purée. Reducing the sugar will change the sweetness, texture, and keeping qualities.
No jam sugar needed: The starch naturally present in chestnuts helps create a thick, spreadable consistency.
Storage: Keep refrigerated at 4°C (40°F) or below. Preferably use within 3–4 days. For longer storage, freeze for approximately 2–3 months for best quality. Thaw in the refrigerator and stir well before serving.
Always use a clean spoon when taking chestnut cream from the jar. This homemade version is not shelf-stable like commercially preserved crème de marrons.
