Add the rice, sake water, and corn kernels to the pot.
Bring to a boil over medium-high heat with the lid off.
Once it comes to a boil, stir once.
Set the corn cob on top.On the day of the shoot, I couldn't find whole corn at the store, so I used frozen raw corn instead.
Cover.
Cook over low heat for 10 minutes.
Turn off the heat, then let it rest, covered, for 10 minutes.
Remove the corn cob.
Gently fluff the corn and rice together before serving.
Notes
Use very sweet, peak-season corn: it gives this Japanese rice its unmistakable seasonal character.Cooking the cob with the rice is essential; it infuses the rice with the sweetness and aroma of the corn.Salting the kernels brings out their natural sweetness, and mixing the sake into the water before cooking helps the seasoning distribute evenly.
