Blackberry Jam

2 quarts of fresh blackberries ( 1/4 of which are unripe), pick near the fence of the cow pasture and look out for snakes and chiggers
6 cups sugar

Wash berries and cook in saucepan over moderate heat until juice begins to flow and berries are soft.  Run through a food mill to obtain juice and pulp.  Measure out 4 cups of juice and pulp mixture and place in preserving pot.  Bring to a boil.  Add sugar and cook over moderate heat until candy thermometer reaches about 221' F (about 30 minutes).  Pour into jars and seal.  Make a cobbler with the extra juice and pulp. Yield: 6 half pints.
