Put one ounce of butter in a saucepan with one tablespoonful of flour kneaded well together. Dissolve it; then add the shelled peas as for No. 977, a bouquet (No. 254), a quarter of a bunch of chives, a pinch of salt, and half a pinch of pepper. Cook in their own juice for twenty minutes, then take the saucepan from off the fire. Pour the gravy from the peas into another vessel, add to it half a cupful of cream and a teaspoonful of powdered sugar; pour this sauce over the peas, and heat up once again without boiling, for two minutes, before serving.
