Cherry Jelly

To Make Juice
Place 1 full gallon of cherries (minus stems) into large pot.
Add 1 cup of water and cook 10-15 minutes mashing the cherries as they cook.
Put cherry pulp through strainer and then place the pulp into a nylon bag and press remaining juice from pits and pulp.

To Make Jelly
3 ½ cups cherry juice
1 tsp butter
1 box dry pectin
4 & 1/2 cups sugar

Place juice in pot and add pectin.
Cook on high heat until it reaches a full rolling boil that cannot be stirred down cook 1 minute.
Add the sugar, bring to a full rolling boil that cannot be stirred down and cook for 1 minute.
Remove from heat, and ladle into jars that have been sterilized for 5-10 minutes (along with their lids and rings).
Apply lids and rings, tighten.

This made 5 pints of jelly.

I had remaining juice and reduced the amounts of sugar and pectin and made a second half batch.
