Before you start make sure to wash jalapenos and onions thoroughly and set your pan on medium heat with the oil.
Place the jalapenos on the pan and begin to fry evenly turning them every two minutes to avoid burning unevenly.
After 25 minutes of turning the jalapenos you should see a nice skin beginning to come thru the jalapenos and your onion should already be nice and fried as well.
Remove your jalapenos from the oil and place minced garlic cloves in the oil to fry for 3 minutes.
Upon frying your garlic your jalapenos should be ready to be combined with the garlic in your blender.
