Mountain regions of Iran · Tart pink rhubarb cooler
Sharbat-e Rivas
A tart, pink cooler made from fresh spring rhubarb stalks — refreshing and energising.

Ingredients
- 500 g rhubarb stalks
- 1 cup sugar
- 2 cups water
- A little mint, optional
Measure and prepare every ingredient, read the complete method once, and keep chilled ingredients cold until the step that needs them. Use a timer, but let the sensory cues guide you.
Detailed method
- 1
Chop the rhubarb and simmer in water until soft.
Technique for this step: Cut and measure ingredients evenly so they cook at the same rate; preheat the pan or pot before the first addition. - 2
Strain and stir sugar into the liquid.
Technique for this step: Control the heat: a steady gentle sizzle is ideal; smoke or a scorched smell means the pan is too hot. - 3
Simmer gently until slightly syrupy.
Technique for this step: Stir slowly and regularly, checking texture at short intervals; uncover only when evaporation is needed. - 4
Dilute with cold water and serve over ice.
Technique for this step: Rest briefly before serving, then make one final check of seasoning, temperature and consistency.
How to know it is ready
Do not rely on time alone: check texture, aroma and colour. The finished flavour should taste integrated, with no raw spice, floury starch or harsh acidity standing apart.
Adjustments & troubleshooting
If it is thin, reduce uncovered over gentle heat; if too thick, add hot water one spoonful at a time. Correct salt, sweetness and acidity at the end, after the flavours have settled.
Make ahead, storage & serving
The drink base can usually be made one day ahead and chilled airtight. Add ice, sparkling water, fresh herbs or ice cream immediately before serving so the texture stays lively.
