"Ketchup is very simple to make and is so much more flavorful than anything you can buy at the store. We don’t like it to be too sweet and like to add only 1/4-cup of sugar to the pot, but if you prefer, add a little more to make the ketchup sweeter. You can also play around with flavors, this version has a kick of spice from crushed red pepper flakes, but you could add fresh jalapeño, chipotle or hot sauce to transform it into spicy ketchup. Other spices are nice, too — try curry powder or garam masala for an Indian-spiced version...."
