When I was young Mayhaw berry bushes grew in the woods on the farm. I used to pick them off the tree and eat them. Now Mayhaw Trees are spring up and the berries harvested to make and sell jelly on line. My niece lives in Louisiana and Mayhaw Berries are a big market there. They will grow in my zone and I'm thinking of ordering a couple to plant in my yard. I have been told the jelly is very good.
TO PREPARE JUICE: Sort and wash fully ripe Mayhaw berries (about one gallon). Crush fruit and add some water (about one cup, cover and bring to a boil on high.) Reduce heat and simmer for 10 minutes. Cool. Extract juice by straining through a juicer wrapped with cheese cloth. Set aside.
TO MAKE JELLY: Measure 4 cups of juice in a large, heavy sauce pan. Bring to a boil, add pectin and stir well. Bring back to a full rolling boil that cannot be stirred down. Add sugar and continue stirring. Heat again to a full rolling boil, boil hard for one minute.
Remove from heat; skim off foam quickly. Pour jelly immediately into hot, sterile canning 1/2 pint jars to 1/4 th inch from top. Seal with hot lids and process 5 minutes in a boiling water bath. Makes 6 (1/2 pint) jars.
