Step 1

In a large pot, start cooking spaghetti in salted water for 9-11 minutes (or follow the instruction on the package.)

Step 2

Meanwhile, start making sauce. Heat up a large frying pan at medium high heat. Pour extra virgin olive oil and add garlic and 1 1/2 tbsp ginger. Cook for a minute or so until fragrant.

Step 3

Next, add yellow onion and shiitake mushrooms. Cook for 2 minutes until onion is translucent. Add water, sake (optional), and dulse flakes. Bring it to gentle boil then reduce the heat to medium.

Step 4

Add passata and season with salt and black pepper. Simmer until spaghetti is done.

Step 5

Drain the spaghetti and transfer to the sauce. Give a quick toss.

Step 6

Serve with the rest of the ginger (1/2 tbsp) and scallion on top. Drizzle some extra virgin olive oil for the finishing touch (optional.)
