Cut the heads and tails off the kippers. Put them in a jug, head end first, and pour boiling water into the jug to fill it, making sure the kippers remain upright. Cover the jug with a plate and leave for 4 to 5 minutes. Pour off the water, and put the kippers on the plate with a knob of butter and a lemon wedge each. Eat some bread and butter with it--it helps the bones go down! Good brown bread and unsalted butter are best.
