Sushi rice in the Instant Pot, is 1:1 water ratio actually right?

Saw a few threads discussing the use of an Instant Pot to cook sushi rice. The ratio that is recommended in most discussions is a 1:1 ratio of rice to water. For sushi rice, the recipe is to take 2 cup of rinsed rice and add 2 cups of water to the Instant Pot. Cover and pressure cook the rice for 12 minutes with the Rice program on low pressure.
What method do people use to release the pressure? Natural release throughout the entire process? Quick release right away at the end of the cook? Both methods (NPR for 10 minutes then QR the rest)? For sticky rice such as sushi rice, I would think that natural release would produce the best texture. Quick release is faster, but the claim is that the rice will still come out proper if you properly rinsed the rice prior to cooking.

The 1:1 ratio is correct for the Instant Pot because it’s a sealed environment. When cooking on the stove, you lose some of the water to steam, so you would need more water.
 
NPR for the full 10 minutes. I’ve made this rice hundreds of times and I always use NPR. The alternative releases the starchy water all over the valve on the pot. I make this rice for sushi rolls.
 
does the rinse step actualy do anything if you’re using a higher quality rice like tamanishiki? or is it more for the cheaper stuff
 
12 minutes is too long. I do 5 minutes of low pressure and then 10 minutes of NPR and it comes out perfect.
 
lol 12 minutes on low pressure for 2 cups of rice? Why not overcook the rice to perfection? Mine is 4 minutes on high pressure, 10 minutes of NPR.

High pressure is not recommended for sushi rice because it can ruin the rice grains. That is why there is a low pressure setting for sushi rice. Do not give people bad advice on how to cook their rice.

ruins it according to who, you? I made it for some of my Japanese friends and they said it tasted better then what they cook in their kitchens at home. Cope harder bro.
 
You must rinse the rice a TON for the 1:1 recipe. Once when I skipped it, the rice was gummy and paste-like. I have to rinse the rice until the water becomes clear, which takes about 4 changes of water.
 
The rice program on the Instant Pot is not the same across all models. The Duo Nova model holds higher heat than most of my friends' units. I’ve found that the 12 minute setting with low pressure is different depending on the model of the Instant Pot you purchase.

yeah this is the part nobody talks about when they explain how to cook rice in an IP.

wait is the rice button for low pressure or high pressure?
 
I soak my rice for 30 minutes prior to cooking and use 1:0.9 rice to water ratio. This makes the best nigiri rice.

soaking rice before pressure cooking does nothing. The rice would cook just as quickly in pressure cooking as it would without soaking. This is just an extra step people add into the process.

soaking rice does not happen in a pressure cooker so soaking rice prior to pressure cooking is pointless. The rice could have been cooked in pressure without soaking and it would have taken the same amount of time. The reason why rice cookers have a soak phase is to allow people to cook rice without a pressure cooker.
