Notes
Based on your personal taste preference you can choose to keep the seeds and the membrane in the jalapenos, or remove them before you chop them up and add them into the salsa. Make sure you choose the best quality, Hass avocado for this recipe. It really makes all the difference. I would recommend making the avocado Pico de Gallo a few hours in advance and letting it sit in the refrigerator. This will help the flavors develop even more. If you have any leftovers, you can transfer them to an airtight container or a mixing bowl and cover it up with some cling wrap before refrigerating it. It should stay good for up to a couple of days.
