In all transparency, I get many of my summer garden vegetable recipes from one of my favorite cooks -- Mike H., of Chili Pepper Madness. We're a house full of heat lovers here so his recipes always hit the spot for us. This spicy ketchup recipe is no different.

HOW TO MAKE SPICY KETCHUP

 1. Heat the oil in a medium sized pot and add the onions and peppers. Cook them down for about 5 minutes to soften them up. Add the garlic and cook for a few minutes while stirring.

2. Add the diced tomatoes, brown sugar, apple cider vinegar, tomato paste, Worcestershire sauce, chili powder, ground mustard, cloves, allspice, black pepper and salt to taste and stir. 

3. Bring to a boil, then reduce the heat and simmer for 45 minutes or up to 1 hour to let the flavors develop.

4. Puree the mixture in a blender or food processor and process it until nice and smooth. (I used the Ninja Blender Auto IQ.)

5. Strain the ketchup through a fine mesh sieve (if necessary) to give it a nice, smooth texture.

6. Store in airtight containers in the refrigerator. I used a squeeze jar with an attached top that closes securely. 

Your homemade spicy ketchup should be good in the refrigerator for 3-4 weeks, or up to 6 months in the freezer. 

It's obviously great for things like French fries, but it's also tasty for chicken nugget dipping sauce as well as a condiment for hamburgers and hot dogs. The possibilities really are endless! 

It's always a treat to have fresh homemade sauces from the garden. In my book, Mother Nature never disappoints! 

Well, that's it for today, friends!
