Wash the rice until the water runs clear. Drain all the excess water from the rice and set a side.
Turn on the instant pot. Heat one tablespoon of oil and add ½ of a diced white onion, 1 large poblano pepper, ½ serrano pepper and 3 large garlic cloves. Saute for 4 minutes and remove.
To a blender add ¼ cup cilantro and the sauteed ingredients. Blend until pureed.
To the same instant pot add 1 tablespoon of oil and the rice and saute for a minute, mixing continuously. Turn off the heat and add 1 & ½ teaspoons of cumin powder. Mix it well.
Now add the pureed mixture, ½ cup corn, 3 slices of chopped pickled jalapeno and 1 & ½ cups of vegetable stock or water. Add additional ¼ cup of water/stock if you prefer slightly softer rice.
Cancel the sauté mode, secure the lid and adjust the vent to sealing position. Pressure cook on high for 5 minutes and do a natural release or wait atleast 12 minutes before releasing the pressure.
Finally add the zest of one lime, ½ lime juice, chopped cilantro and mint (optional). Gently fluff the rice, taste and adjust the salt and lime.
