1/2 cup (120 grams) long grain or short grain rice
8 cups water
1 stalk lemongrass (or 2 stalks if you like a very strong lemongrass flavor)
3 cups diced kabocha squash (the yield from half a kabocha squash)
1 cup sweet corn kernels
4 cups spinach
(Optional) 1 bunch of Thai basil leaves for garnish
Sambal and/or fried shallot for serving
Add rice and water to cover in a large bowl. Use your hand to gently swirl a few times to rinse, discard the water. Repeat 1 to 2 times. Drain rice and transfer into an Instant Pot. Add 8 cups water.
Cut the lemongrass into 2-inch (5-cm) stalks and pound them with the back of your knife, to bruise the stalks so they release more aroma. Add the lemongrass into the Instant Pot. Set the pressure to high and timer for 15 minutes. Once the timer is up, use quick release to reduce the pressure.
Add the diced pumpkin. Cover and cook on high pressure, for another 6 minutes. Use natural release to reduce pressure.
Add the sweet corn kernels and turn on the saute function until bringing to a boil. Cook with the lid two-thirds of the way covered for 3 to 5 minutes, until the corn is cooked through.
Add the spinach and continue cooking for a minute. Turn off the Instant pot.
Transfer the porridge into serving bowls. Serve hot with sambal and / or fried shallot.
