6 lemons 6 oranges 4 lb.. sugar 2 oz. citric acid 2 qt. boiling water
Grate rind of oranges and lemons then squeeze out the juice. Put grated rind, pulp and juice into a big pot and add remaining ingredients. Stir and let stand overnight. Strain and bottle in sterilized jars. To reconstitute - mix 1 part to four parts water. (The strainings make good marmalade - just add some more sugar and enough water to keep the mixture from scorching - simmer until peel is soft, then bottle.)
