The title of this entry could also be called: Ketchup attempt #1, almost ketchup, Tomato-based sauce, or hmm not quite ketchup. This recipe has been kicking around since 2011 from the NY Times . I really based it very loosely on this recipe since when I made it following their directions, it came out very loose. I didn't even add the water as suggested and I had to cook it to make it thick. It is nonetheless quite good but I would not exactly call it ketchup. Not very pleasant looking in the food processor Ketchup Wannabe 3 tomatoes 3T vinegar 1 garlic clove 1/3 t ground cloves 1/3 c sugar 1T maple syrup 1/4 t sriracha (or cayenne pepper) 1T Worcestershire sauce 1t ground mustard seed 1T cornstarch Slice the top off the tomato and squeeze the seeds out. Place the tomatoes in a food processor. Add the remaining ingredients. Puree. Pour into a small saucepan and simmer until thickened to a ketchup consistency. Looks like Ketchup Now this might not be ketchup...
