The chestnut is definitely a fruit that symbolizes fall. Available from mid-September onwards, there’s a six-week time frame during which ripe chestnut can be harvested.
It’s of course a joy to the taste buds all the way to the Christmas season!
A source of food since Prehistorical times
Belonging to the same family as the oak tree, the chestnut tree species prospered during the Tertiary period. Mankind has been harvesting its fruits for thousands of years. Its wood is used to build and furnish homes. Tradition honors it as the “food tree” that best fulfills its purpose among its peers.
Growing and caring for this tree has made it possible for peoples of mountain areas to survive even where growing grain crops is impossible. In some areas like Corsica and the French Cévennes, chestnut is called “poor man’s meat”.
To this day, over 700 specific varieties have been catalogued by the French National Agronomic Research Institute (INRA).
Don’t confuse it with its cousin, the horsechestnut
At first glance, it seems difficult to spot the difference between a chestnut and a horsechestnut (or conker). However, their shape says it all. When cracking the husk open, a chestnut will break into fragments whereas the horsechestnut will stay whole.
Note that the fruit of the horsechestnut tree (species most commonly found in Europe) isn’t edible. As for the chestnut, best is to choose it shiny and flawless.
Savor it stir-fried, boiled, in soups, mashed…
Chestnut and squash lamb navarin stew
Good for 4 persons
- 7 oz (250 g) chestnut
- 2½ pounds (1.2 kg) deboned lamb shoulder
- 1 onion
- 5 cloves garlic
- 1 sprig of thyme, 1 bay laurel leaf
- 8 fluid ounces (25 cl) walnut wine
- 1 table spoon flour
- 2 table spoons sunflower oil
- 10 oz (300 g) squash
- 1 table spoon walnut oil
- salt and ground pepper.
Dice the lamb shoulder into large cubes. In a cast iron cooker, fry the lamb at full heat for a few minutes with the olive oil, just for the outside to turn brown. Add salt and pepper. Crush the garlic cloves while still in their husk and toss them in the cooker together with the onion (diced), thyme and laurel. Sweat the spices for a few minutes and add the walnut wine to deglaze the cooker. After boiling off some of the liquid, add flour and stir. Pour 8 fluid ounces (25 cl) of hot water and stew for 1 and ¼ hours at low heat. Peel and dice the squash. Incorporate the squash cubes and the chestnuts in the cooker and cook for a further 15 minutes. Pull the cooking pot from the stove, add in the walnut oil and stir. Serve directly from the pot.
