Prepare your leek and let it soak to remove any residual dirt. In a frying pan, melt your butter and add the shallot. Once your leek is washed, drain and add to the pan. Season and cover to let the leek soften. Depending on how large your leek piece are, this can take anything between 10 to 20 minutes.

Bring the salted water for your pasta to simmer. Add your chosen pasta and cook following the instruction on the packet. On average no longer than 12 minutes. You can now decide whether you want to blend part of your leek to a smooth puree or leave it as is. Drain your pasta, add to the leek and coat with the soften vegetable. Finish by adding the saffron milk and pistils, add your grated cheese and serve. Buon appetito!
