Final Thoughts

Harvest & Selection: Only fully ripe, mature chestnuts are chosen—large, unblemished, and free of moisture.
Cleaning & Opening: The outer husk is removed, and each chestnut is dried thoroughly.
Seasoning: Lightly salted or dusted with sugar before roasting.
Roasting: Cooked slowly over open flames or low heat to develop deep caramelization and a glossy, dark crust.

The result? A rich, sweet aroma with hints of toasted hazelnut, soft in the center but with a satisfying crunch on the outside.
