Mine never last more than 3 day's!!
Depending on taste: You can cut back or add ingredients.
Some people don't like cilantro. You could add Green Bell Pepper and or if to hot remove seeds from Jalapeno Peppers "BEFORE" adding to blender.
Add 3/4 cup water to sauce pan - bring to boil
Add quartered tomatoes and steam till skins peels away.
**DO NOT OVER COOK OR LET WATER BOIL AWAY**
Turn peppers to toast as many times as peppers will allow.
*** LEAVE STEMS ON PEPPERS UNTIL YOU ADD THEM INTO BLENDER AND AGAIN DON'T OVER COOK / BURN
When mix is blended fine add tomatoes!!
