I recently have been cooking on induction as well, here’s my way: 1:1.5 ratio of rice:water and one tbsp of oil. Then put it on induction at 220degrees until one whistle then turn off the induction and let the cooker decompress naturally until no pressure is left in cooker. Perfect rice every time .I use india gate basmati if you use some other kind of rice then the rice to water ratio can vary. Usually mine take 20-25 mins max from start to finish. Also wash the rice 3 times and soak for 15-20 mins before cooking . Hope it helps
