This wholesome drink combines the nutty, earthy flavour of pearl barley with the bright zest of fresh lemons, creating a perfectly balanced refreshment that's both nutritious and delicious.

Ingredients You'll Need
Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.
- 100 g pearl barley (washed and drained)
- 1.2 litres water (for cooking barley)
- 80 g rock sugar or cane sugar (adjust to taste)
- 3 medium fresh lemons (juiced)
- 2 cups ice cubes (for serving)
- 1 lemon lemon slices (for garnish)
Step-by-Step Instructions
- 1
Rinse the pearl barley under cold running water until the water runs clear, removing any dust or debris. This ensures a cleaner-tasting final drink and prevents cloudiness.
~3 min
Tip: Use a fine mesh strainer to prevent losing any barley grains - 2
In a large pot, bring 1.2 litres of water to a rolling boil over high heat. The generous amount of water ensures the barley cooks evenly and doesn't stick to the bottom.
~5 min
- 3
Add the washed pearl barley to the boiling water and stir gently to prevent sticking. Reduce heat to medium-low to maintain a gentle simmer.
~2 min
Tip: Stirring prevents the barley from clumping together - 4
Simmer the barley uncovered for 35-40 minutes, stirring occasionally, until the grains are tender and the water has taken on a slightly milky appearance. The liquid should have a subtle nutty aroma.
~40 min
Tip: Test a grain - it should be soft but still hold its shape - 5
Add the rock sugar to the hot barley mixture and stir until completely dissolved. Taste and adjust sweetness as desired - you can always add more sugar later.
~3 min
Tip: Rock sugar dissolves more slowly but gives a cleaner sweetness - 6
Remove from heat and let the mixture cool to room temperature, about 15-20 minutes. This prevents the hot liquid from cooking the lemon juice and creating a bitter taste.
~20 min
- 7
While the barley cools, juice the fresh lemons using a citrus juicer or by hand, removing any seeds. Fresh lemon juice is crucial for the best flavour.
~5 min
Tip: Roll lemons on the counter before juicing to extract more juice - 8
Strain the cooled barley mixture through a fine mesh strainer into a large pitcher, pressing the barley gently to extract more liquid. Reserve some cooked barley grains if desired for texture.
~5 min
Tip: Don't press too hard or the drink will become cloudy - 9
Add the fresh lemon juice to the strained barley liquid and stir well to combine. Taste and adjust the lemon-to-sweetness ratio according to your preference.
~2 min
- 10
Chill the drink in the refrigerator for at least 2 hours until completely cold. The flavours will meld together beautifully during this time.
~120 min
Tip: Cover the pitcher to prevent absorbing other fridge odours - 11
To serve, fill glasses with ice cubes and pour the chilled barley lemon drink over the ice. Add a few cooked barley grains to each glass if desired for texture.
~2 min
- 12
Garnish each glass with a fresh lemon slice and serve immediately. Stir gently before drinking as the barley liquid may settle slightly.
~1 min
Tip: Serve with a spoon if including barley grains
How Do I Know It's Ready?
The barley is perfectly cooked when individual grains are tender but still hold their shape, and the cooking liquid has turned slightly cloudy with a subtle nutty aroma. The drink is ready when it's well-chilled and the flavours have balanced - not too sweet, not too tart.
Frequently Asked Questions
