The foundation for this 1:1 recommendation is due to two things being true:
1. The Instant Pot allows very little water evaporation due to Instant Pot’s superior sealing ability.
2. Rice absorbs its volume in water when cooked long enough.
Reviews have been overwhelmingly positive, no more mushy rice, with a few stating the rice was cooked, though a bit too “al dente” for their preferences, (these individuals where happier when using a small amount of additional water). Consider this your starting point, record any adjustments you may make, and soon you will have your personal recipe for perfect rice in the Instant Pot!
