Pear Preserves from Free Pears, Homemade

Pear preserves from the pears I picked yesterday. Only got 4 jars out of all those pears. Granted they were bigger jars and not the half-pint jars, because evidently there is a jar shortage continuing from last year. Anyway, we got what we got.
Ingredients were fairly simple.
16 cups of peeled, cored and cut up pears
4 cups sugar
2 cups water
3 tablespoons lemon juice
2 teaspoons vanilla extract
1 packet pectin
Cook pears, sugar, water, vanilla and lemon juice in a large pot for about 1 1/2 to 2 hours. When they are at that point add the pectin continue cooking for 1 minute. Remove from heat and immediately start ladling into jars. Fill to within a 1/4" of top of jar. Let settle for a minute, working out any air pockets. Wipe the rims of the jars well. Install lids and tighten finger tight.
Lower jars into canning pot, bring already warm water to a rolling boil. Then set timer for 10 minutes. Remove jars from canning pot using a jar lifter. Remember these things are hot as can be. Set the jars on counter and let cool. After they have cooled check the lids to make sure they vacuum packed correctly.
