let's cook black rice

all you got to find out, is the exact volume of extra water needed for evaporation

Most common question asked, how much water does black rice need to cook? You may have a ratio that has been working out well for you, but here what we feel gives that ideal 'chewiness', not too hard, not moist either.

Key is to take into consideration that not only water is absorbed into the grains, but that along the process a bit of water evaporates.

Let's break both parts up here.

first, absorption

rice-to-water ratio for black rice
1 cup of rice

1 cup of water

If you double your batch of rice, double the volume of water.
If you triple the rice, then triple the volume of water.

second, evaporation

1. some water 'escapes' while boiling rice, this loss has to be compensated

water evaporates

This amount of water depends on your cooking equipment and will always be the same volume, regardless how many batches you decide to cook.

2. find out the amount of evaporation water

gradually add water and taste

Cook first 1 cup of rice with 1 cup of water.

Taste and most likely you will find the texture a bit hard. Add ¼ cup of water. Simmer until all water is gone (keep lid covered). Taste again and repeat until you got the texture that works for you.

Probably you end up somewhere between ¼ (harder texture) to ¾ (softer, more moist) of a cup.

3. volume of water for evaporation is fixed regardless the total amount of rice

________  ratio

rice-to-water ratio for black rice
x cup of rice

fixed volume of water for evaporation

For example at home, when we want to boil 3 batches of rice - out of experience we know that with our equipment ¼ cup of water is vaporized - we got to go with 3 + ¼ cup of water.

then, two more things

don't keep rice at room temperature

Either hold the rice warm or refrigerate.
Also, reheat overnight leftovers.

soaking rice result in loss of anthocyanin

a little bit of explanation here

cooking black rice with a rice cooker

boiling rice on a stove/with a pot

to cook black rice

Bring rice to a boil for 5 minutes. Cover and simmer (medium-low heat) for 25 minutes.

Use the same cup to measure the amount of water.

to cook black rice

Fluff the rice and simmer for another 5 minutes.
(get a heavy-bottom pot - we can't stress enough - to avoid the rice to burn or stick)

to cook black rice

Turn off the heat and let the rice be for 15 minutes so the grains can firm up.
keep the pot covered all the time, also at the end when the rice sits.

cooking instructions for rice cooker and pressure cooker/instant pot

Often we are asked, what's better: pot or rice cooker?

We feel rice is tastier when using a pot, but a simple rice cooker works just fine, and that's what we - and most people in Thailand - use most of the time.

It's so easy, just follow your rice cooker's rice-to-water ratio recommendation and once ready, the device will shut itself off while the rice is kept warm!

Nevertheless, you can determine the amount of evaporation water the same way as described above.

We are not familiar with pressure cookers, but the same goes here. Define the water volume for evaporation as you would do with a pan. One of our customers told us that an absolute fool-proof method is to go with a rice-to-water ratio of 1:1 and seal. Cook 40 minutes on high pressure and then let it naturally release for another 20 minutes.
