Homemade Hot Sauce
This homemade hot sauce makes good use of the bountiful tomatoes, onions and peppers in your garden or farmers' market. Adjust the heat to your preference: in our tests, two habaneros yielded a pleasantly spicy sauce without excessive heat--take it up a notch for spicy-food fans by adding extra hot peppers.
Tip: The membranes that hold the seeds are the spiciest part of chile peppers (that's where the capsaicin is). The seeds pick up some spiciness by association. You can customize the heat of salsa or hot sauce by using some or all of the seeds along with the flesh of the pepper and tasting as you go. Be sure to wash your hands thoroughly after chopping hot peppers or wear rubber gloves.
To make ahead: Cover and refrigerate for up to 1 month or freeze in an airtight container for up to 6 months.
