Salsa Mexicana
This chile pepper gets its name from its origin. In Spanish, serrano is an adjective meaning “from the mountains” which is where it originated-in the mountains of Hildalgo, Mexico. The serrano is normally about twice as hot as Jalapeno (about 10,000 to 15,000 Scoville units). It is the second most popular chile pepper in Mexico. This chile is used mostly for salsas but can also be used in soups, sauces, chili or stews. Try these as a hotter substitute for Jalapeno.

3 Roma tomatoes, diced
2 fresh serrano chiles with seeds, diced
1/2 medium onion, diced

Kosher salt
