You can substitute bell peppers for some or all of the long, green chilis. Canned chilis may be used in place of fresh. Use only high quality peppers. Do not increase the total amount of peppers in any recipe. You can, however, substitute one type of pepper for another.
Spices add flavoring to salsas.
Cilantro and cumin often are used in spicy salsas. You can, however, leave them out if you prefer a salsa with a milder taste. For a stronger cilantro flavor, add fresh cilantro just before serving the salsa. Heat to a boil and simmer 10 minutes. Process in a boiling water canner for 15 minutes, or for 20 minutes at altitudes over 1,000 feet.
