Naturally dried, they have been matured during 2 years.

Our perfect combination :
 - For a consistent dashi, dilute 50 g of kombu in 1/2 liter of water ; for a light dashi, dilute 25 to 30 g of kombu in 1/2 liter of water (to rehydrate, leave it to marinate at room temperature for 6 to 12 hours, then cook slowly)
 - Set the kombu in cooking pot with cold water and bring water to +80°C +85°C (not higher)
 - Remove preparation from the stove and let infuse for 10 min (you can also continue cooking / reheating preparation slowly for 10 more min to get more favors).
A gentle water will let the kombu seaweed express all its aromas.
Use the broth for fish stews, vegetables cooking, ramen...
