Set aside. Roast the fingerling potatoes in oven for 15 minutes or until they are fork tender. Peel and blanch the asparagus in salted boiling water until al dente. Saute the morels with the spring peas and butter until tender. Blanch, shock and puree the watercress in a blender with the cream and 2 tablespoons grape seed oil for a fine puree.
