Slow Cooker Ketchup

This ketchup is simple, made with ingredients you have on hand, and makes a wonderful gift.  It is excellent on meat loaf.  I hope you try it!

1 28 oz. can crushed tomatoes
1 6 oz. can tomato paste
1 onion, chopped
1/2 c. cider vinegar
1/4 c. firmly packed brown sugar
1/2 tsp. dry mustard
1/4 tsp. allspice
1/4 tsp. cinnamon
1/4 tsp. nutmeg
1/4 tsp. ground ginger
1/4 tsp. ground cloves
1/8 to 1/4 tsp. cayenne to taste
a few grinds black pepper
salt to taste

Combine the tomatoes, tomato paste and onion in a food processor and process until smooth.  If you have a hand blender you can do this step right in your slow cooker.  Add the vinegar, brown sugar, mustard and spices.  Pulse to combine.  Add to slow cooker.  Cover and cook on high for 2 hours, stirring occasionally.  Remove the lid and continue cooking on high for another hour or so until it reaches the desired consistency.  You want it to plop off of the spoon. 

Store in a clean quart sized jar in the fridge.  It will keep for up to 2 months.  Be sure to make something to serve it on the night you make it- it is excellent warm!
