Once the pressure has been released, open and adjust water and salt. Allow to simmer for 2-3 minutes on the saute setting. This step is optional, but will allow the beans to thicken up a little bit more.
Garnish with cilantro and serve!
Notes
You could cook the beans for 20 minutes, but 30 will give it a thickness that seems like you kept it on the stove for hours. Feel Free to remove the seeds from jalapeño if you can't tolerate spice.
