Step 1

Combine all ingredients until smooth in a saucepan.

Step 2

Bring to a boil, reduce heat to low and simmer 15-20 minutes (you'll need to partially cover because it will spit hot tomato out at even the lowest simmer). If it seems too thick, add water, a teaspoon at a time to desired consistency.

Step 3

Let cool and then pour into a glass bottle for storage (a metal funnel makes this easier).

Step 4

Keep refrigerated. If it thickens too much in the fridge, just add some water (a couple teaspoons at a time) to reach pouring consistency.
