In Tim Anderson's Japaneasy he instructs to cook 300g of rice in 390g of water (1:1.3).
He also says to rinse the rice first. When I rinsed the rice and weighted it again after letting water drain, it now weighs 348g.
Should the amount of water I add to the pot to cook it be 390g? Or 342 (subtracting the amount of water absorbed by/clinging to the rice already).
