Homemade Ketchup

Well, I've become one of those people that makes their own condiments.  As a recovering Heinz snob/ketchup whore, this is a HUGE step for me.  This is the recipe that I've played with for awhile and I find that it tastes pretty close to Heinz ketchup (minus the nasty corn syrup and the questionable "natural flavours")!  Let me know what you think!

Ingredients:

12oz tomato paste (I think the Kirkland organic - it's two small cans worth)
1 cup white vinegar
1 cup honey
1/4 cup water
2 teaspoons sea salt
3/4 teaspoon onion powder
1/8 teaspoon garlic powder
1/8 teaspoon allspice

1.  Combine all ingredients in a large sauce pan.
2.  Heat over medium-high heat until boiling.
3.  Reduce heat and simmer until ketchup reaches desired consistency (approximately 15-20 minutes).
4.  Pour into mason jar (1L) and allow to cool.
5.  Refrigerate.
