Slice jalapeño lengthwise and remove membrane and seeds. *For spicy salsa, leave some membrane and/or seeds.

Notes
Recipe Variations:
Adjust the ratio and type of produce Because this is a jalapeno tomato salsa, the red color is more prominent. To create a green color without increasing the spicy heat, substitute tomatillos for some or all of the tomatoes.
Roast the vegetables It takes a bit more time, but roasting the tomatoes, garlic, and jalapenos adds a deliciously smoky, almost earthy flavor to your food processor salsa. Tomatoes become sweeter, peppers become more intense, and the garlic becomes creamy and nutty. After roasting, remove the charred skins to remove any bitterness or strange texture.
TFN Pro Tips:
All spicy chiles contain a natural chemical called capsaicin that can burn sensitive skin and membranes like the eyes and sinus cavity.
For your protection, it’s best to wear disposable kitchen gloves when working with jalapenos and other spicy peppers.
The longer you cook the vegetables, the looser the salsa's consistency will be. For a thicker consistency, pour off juices before processing.
Storing Instructions
Homemade jalapeno salsa will be kept for up to 3 days in the refrigerator. Honestly, it’s more delicious after the first day, as all of the flavors will meld together!
While it is possible to freeze salsa for a few months, this isn’t the best option for a thin salsa. The liquid tends to crystallize like an ice cube, and this can affect the flavor.
