This recipe is a great starting point to develop your own Mexican salsa recipe. Adjust any or all of the ingredients to suit your tastes. Although this recipe calls for charring the chiles, you can also make it without charring them. Add more chiles for a spicier sauce or reduce the number for a milder version. Substituting jalapeño chiles for the serrano chiles will make a milder salsa too.
I think that garlic will work fine. You can use a water bath canner or a steam bath canner – but you need either one of those to properly seal the jars. Sorry for the incorrect link. I’ve fixed it: https://www.amazon.com/gp/product/B0000DDVMH/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=melskitcaf0b-20&creative=9325&linkCode=as2&creativeASIN=B0000DDVMH&linkId=2b53645dcd7f209be06b0641dbb4edab
Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil over high heat, then carefully lower the jars into the pot using a holder. Leave a 2 inch space between the jars. Pour in more boiling water if necessary until the water level is at least 1 inch above the tops of the jars. Bring the water to a full boil, cover the pot, and process for 10 to 15 minutes.
Mexican food, essentially, mirrors the country of Mexico itself: a proud indigenous culture attempted destroyed by an overpowering invading force but managing to somehow withhold enough principles and key elements to remain entirely its own while becoming something decidedly new: A mix of tradition and innovation all stirred up in a melting pot for some 500 years to create flavors that are neither Mesoamerican nor Spanish, but decidedly Mexican: hearty, comforting, powerful, colorful and full of spice!
Step 11: Some of you may not like spicy salsa. I get that. Add a small amount of jalapeno, about a tbsp. anyway. The tiny amount will not add much spiciness, but it will add a nice depth of flavor. If you like your salsa really spicy, add as much as you like, or even try a spicier pepper. I just want an obvious kick, but nothing too hot. About 2 tbsp. was enough for me. Remember that the salsa will get spicier as it cooks and processes.
The problem with simply heating up the sealed jars is that during normal processing, the goal is to drive all air out of the headspace (the space between the food and the lid). That’s why you only put the lids on finger tight instead of cranking them on as tight as you can. While boiling, the air is forced out, and then the vacuum formed by lack of air sucks down the lid, making a tight seal. No air trapped in the top of the jar = no opportunity for microorganisms that need air to grow to spoil your salsa. If the pH is low enough, botulism (which releases spores in an anaerobic (no oxygen) environment) will also be out of commission.

As you will notice when we dive a little further into these recipes, Mexican food has a stunning range of somewhat special ingredients. From Masa Harina, the essential ingredient of corn over a wide array of chilies either fresh, dried or ground to Mexican oregano and tomatillos. Some of these may at first glance seem foreign and difficult to come by, but fear not we’ll discuss the individual ingredients as we go and they’ll be easier to come by than you think.
