Adapted from Nom Nom Paleo. This is my go-to recipe for delicious pulled pork in only 90 minutes at pressure. For a 2-person household, I coordinate with my step-daughter so we can both enjoy this economical but delicious protein. One Boston Butt yields a lot of pulled pork! Note that cooking time is the amount of time cooked at high pressure (as is common for pressure cooker recipes); the pressure cooker can take 10-25 minutes to reach high pressure, and from 15-25 minutes to naturally release pressure.
