While traveling through Norway, Chef Rosendale discovered this technique from friends in Stavanger.

The process transforms leeks into a rich, smoky powder that adds depth and complexity to many dishes. Use it to enhance mousses, layer with pork loin, or sprinkle over vegetables, cheese, and fish. A small amount delivers a bold flavor, so use sparingly—and feel free to experiment with other vegetables for creative variations.

Part 1:
Leek Ash

Step 1

Pre-heat oven to 425 degrees F. Remove the white of the leek and reserve for other preparation. For the ash, only use the leek greens.


Step 2

Separate leek greens from one another. Rinse leek tops and dry thoroughly. Once dry, place on a sheet tray with a roasting rack.


Step 3

Roast leek tops until black, 90 minutes to 2 hours. Once black, remove from oven and let cool to room temperature.


Step 4

Once cool, pulverize leek tops in a coffee grinder until you get a fine powder ash. Store in a cool dark place.
