This is a very fine thing.
5-inch Piece of Fresh Horseradish, peeled
Juice of 1/2 Lemon
1 1/4 c. Crème Fraîche
Sea Salt and Freshly Ground Black Pepper
Finely grate the horseradish. This can be quite an emotional experience and may bring tears to your eyes, but is very good for clearing the sinuses.
Sprinkle the grated horseradish with lemon juice to prevent its discoloring.
Mix gently with the crème fraîche and season to taste.
