Grandma's Blender Ketchup

I love this recipe.  Just thinking about this recipe makes my mouth water.  My mom has made this recipe annually with the tons of tomatoes they have grown through the years.  Although it it called 'ketchup,' it doesn't have the consistency of store-bought ketchup- it's more like a barbeque sauce and my parents actually use it as a barbeque sauce. 

For a quick meal, I use the ketchup to make sloppy joes- brown ground meat and drain the fat; add a jar and heat.  Makes great sandwiches- fast and easy.

*I use my food processor instead of a blender.


BLENDER KETCHUP
8 lbs. of  ripe tomatoes, about 48 medium size 
2 sweet red peppers, medium size **
2 green bell peppers, medium size
4 onions, medium size
3 cups vinegar
3 cups sugar
2 teaspoons salt
3 teaspoons dry mustard
1/2 teaspoon red pepper, omit
1 1/2 teaspoons ground allspice
1 1/2 teaspoons ground cloves
1 1/2 teaspoons ground cinnamon

Quarter tomatoes; remove stem ends. Add peppers, seeded and cut into strips, and onions, peeled and quartered. Mix.
Put vegetables into food processor. Pulse off and on until vegetables are pureed and pour into a large pot. Repeat until all veggies are pureed.
Add remaining ingredients; stir to mix thoroughly. Bring to boil over medium heat; lower heat and simmer, uncovered until volume is reduced by half.
Pour into hot, sterilized jars. Process in boiling water bath for 10 minutes at 212 degrees.

**I use 4 green peppers.
