Step 1

First take the barley grains in a plate and pick, discard if any stones in them.

Step 2

Rinse the grains in a strainer for a couple of times. Next, there is the option to soak the grains for 4 to 5 hours or overnight. (See notes)

Step 3

Next, proceed based on your cooking method:Instant Pot: Add the prepared grains to the steel pot of the IP. Pour in 5 cups of drinking water. Barley grains increase in volume a lot, so you may need to add more water while cooking. If you prefer a more concentrated barley water, only add 4 cups.Pan on a stove top: Add barley grains to a large pot with a tight fitting lid. Add 4 cups water. Stove-top Pressure Cooker: Use at least a 3 to 4-litre pressure cooker as the water bubbles and froths while cooking. Add 4 to 4.5 cups water.

Step 4

Cook the soaked pearl barley.Instant Pot: Seal the lid and position the pressure release valve to sealing position. Press the pressure cook/manual button and pressure cook on high pressure for 20 minutes. When you hear the beep sound after the cooking is complete, wait for 10 minutes and then do a quick pressure release. After all the pressure and steam is released then only remove the lid. Pan on a Stove top: Place the cover on the pot and cook for 30 to 35 minutes. Stove-top Pressure Cooker: Cook for 12 to 15 minutes (or for 8 to 9 whistles) on medium-heat. After the cooking is complete, when the pressure falls naturally in the cooker, then only open the lid.

Step 5

You will see a cloudy, opaque water and the barley grains all plumped and softened.

Step 6

Let the water cool enough to handle. Strain the grains from the water using a mesh strainer. Lightly press the grains with the back of a spoon to extract the most water.

Step 7

Add lemon juice according to your taste preferences. Finally, add your sweetener of choice or omit the sweetener. Stir to combine. (For more flavoring ideas, read the notes below)

Step 8

Pour in glasses and serve. You can serve barley water warm or cool depending on your preference. Feel free to garnish with some mint leaves if you like. Refrigerate any leftovers for a day only.
