Fresh Ingredients Make the Best Salsa

Fresh ingredients always make the best salsas. Make sure that your tomatoes are really red and ripe which gives the salsa better color and a richer flavor. Really fresh cilantro gives the salsa a nice herbal tang. Avoid tired wilted cilantro because it has lost much of its flavor.

Remove the stems, then slice the serrano peppers in half and remove the seeds. You can leave the seeds in if you prefer. This will add more heat to your salsa.

    stupid question but would you serve the Salsa hot, cold or either?

  • P.M.

    I followed this recipe and it worked out really great, still I had to do some changes and substitute the Serrano chiles with a lot of dried De Arbol chiles and no cilantro. Just use water enough to be able to blend the vegetables. Always boiling everything and reducing at the last to really thicken it. Take your time seasoning. It came out really hot just the way I like it. I loved it.

  • Maire

    You have stated 2 cups of water in the ingredients list and 4 in the method

  • Marvin

    Absolutely no flavor. Not spicy at all. Glad I wasted my time on this!

  • Megan

    After reading all the bad reviews I had to reply. I have been making my own salsa for many years, but always a fresh salsa and having been searching for am authentic recipe like this one. I love the recipe, have been making it over and over and find it absolutely delicious. I never add much of the cooking liquid, I just save some and use it to thin as needed. I love the simplicity of this recipe and the depth of flavor is incredible, and it really does taste better and better as it sits. Everyone I’ve served it to has raved about it. I always uses the freshest, highest quality ingredients I can find, maybe that i enhances the flavor as well. I use organic Roma tomatoes.

      We also have made this salsa. It was great and everyone loved it.

  • Amy

    Can I can this recipe???

  • AL

    Absolute terrible recipe. Followed to a T and as everyone else has mentioned, ended up with what I can only imagine dish water tastes like after cleaning Michelada glasses.

    Look elsewhere (also suspect this recipe has no lime). Terrible this even comes up in the google search it’s so bad.
