Put into a saucepan two ounces of butter and one ounce of flour. Place on a slow fire, and with a spatula stir slightly for two minutes, adding two ounces of sugar, half a gill of Madeira wine, and one gill of Middletown milk; stir well again for two minutes, to avoid its coming to a boil. Then take it from the fire, and immediately add half a gill of rum, stirring it slightly again. Pour the creme into a sauce-bowl and serve with the savarin.
