To inspire you, we have asked Jardin des Saveurs chef’s Laurent Brault, to create recipes that will change your view on the use of seaweed in cooking.

Seaweeds are real allies in the kitchen! More than just a flavor enhancer, they are rich in gustatory discoveries and sometimes shake up the taste buds to reach unknown flavors and maybe even Umami! The famous “round in the mouth” flavor which completes the 4 flavors known to all (sour, bitter, sweet, salty).

Cooking with seaweed is the opportunity to develop innovative recipes, to surprise and improve classic dishes. Adding extra nutritional richness without frills to everyday dishes, more or less elaborate.
