700gramsboiled, cooked chestnuts without the shells (this is a yield I got from about 1200 grams of fresh chestnuts)
4cupsmilk, you can use a mild tasting non-dairy version
1½tbspVanilla Bean Paste (or use 1 Vanilla Bean, seeds scraped)
Instructions
Simmer Cooked Chestnuts in Milk
Into a saucepan, pour milk (4 cups), add cooked, peeled chestnuts (700 grams).Bring the mixture to a boil and reduce it to a simmer. Simmer for about 20-30 minutes, until there is only about a 1/3 cup to 1/2 cup of milk left. I like to test the chestnuts to see if they are fork-tender to be sure. If they are not, I add a little more milk and cook for an additional 5 minutes.Be sure to stir the chestnuts, especially towards the end, so they don't scorch at the bottom of the pan.
Puree Soft Chestnuts
To avoid runny puree, strain braised chestnuts (reserving the milk) into a food chopper and blend them until smooth. Add Vanilla bean paste (1½ tablespoons). If the puree is too thick, add some of the remaining milk and blend until thick and smooth.
Freeze Chestnut Puree
Spread a cool, thick chestnut puree onto a parchment paper. Spread it into a rectangle or a square. Cover it and chill it until firm. Cut up the block of chestnut puree into more manageable bars. Wrap each bar in a freezer-safe paper and freeze for up to 12-18 months.
Notes
How long does chestnut puree last? - After it's made, it can be stored in the fridge for up to 14 days.
Can I freeze chestnut puree? I like to make a bigger batch and freeze it for later. When frozen properly, it can last in the freezer for up to 18 months.
This puree is not sweet enough for me! - Sweetness, and color can vary and so if the chestnuts are not sweet, add 1-2 tablespoons of sugar to the milk and cook peeled chestnut in a lightly sweetened milk.
