Use a variable-speed blender or food processor fitted with a steel blade to chop vegetables for this medium-heat salsa. When done, the vegetables should be finely chopped but not slushy. You can also chop the vegetables by hand, which is the traditional way to make salsa.
Before adding the chile to this recipe, however, take a tiny taste of it. If you’re using a fiery hot habanero, you may want to add only a teaspoon of minced chile. If you’re using a milder tasting jalapeño chile, use the whole pod, minus the seeds. (See the sidebar “Some like it hotter” in this chapter for more on chiles.)
