You’ll have already realised That sometimes the term marrons is used, and sometimes chestnuts. But is there a difference between sweet chestnuts and regular chestnuts? A distinction can be made between the three terms: chestnuts, marrons and late chestnuts. Sweet chestnuts have a dark skin, their flesh is difficult to remove from the skin and they have a really short shelf life. Marrons have a particularly aromatic flavour, their flesh is easier to remove from the lighter skin and they also have a longer shelf life than chestnuts. The late chestnuts differ mainly in the fact that they do not fall from the tree themselves but have to be picked.

If you are lucky enough to get hold of fresh sweet chestnuts, they can be kept in the fridge for a few weeks. Fresh sweet chestnuts will stay particularly fresh in the fridge thanks to the innovative refrigeration technologies from Liebherr. A BioFresh safe provides the ideal temperature and moisture conditions to slow down the natural ripening process. This allows sweet chestnuts to retain their aroma, consistency and valuable nutrients for much longer.

When you buy chestnuts, the skins should be smooth and glossy and not have any holes. If you shake a single nut, it should not rattle. Make a cross-shaped incision into the chestnut and roast the nut in the oven or boil it in water until the peel opens - this takes about 20 minutes. The velvety, leathery skin surrounding the fruit flesh is usually quite difficult to remove. It’s easier if you place the peeled sweet chestnuts in hot water for a few minutes.

To start off with, sweet chestnuts are not suitable for consuming raw because they contain very large quantities of tannins. These tannins are the reason for the tart taste. But cooking makes their flavour wonderfully sweet. Half of the nut is made up of water. The other half consists mainly of carbohydrates and also two grams of fat and protein (per 100 grams). The carbohydrates are predominantly starch - this gives the chestnuts their characteristic floury texture.

When compared to other nut representatives (e.g. walnuts or hazelnuts), a feature of the chestnut is their low-fat content of only 2 percent - other nuts usually contain over 50 percent fat.

Marrons are said to strengthen the heart and kidneys because of their nutrients and deliver positive health benefits. Chestnut leaves are also useful as a household remedy. A steamy bath with the leaves is said to help with an irritable cough. First and foremost, however, we love sweet chestnuts for their tasty and versatile fruits.
