Recipe: refreshing summer citrus cooler
Words: Sheryn Clothier
You can dress this up with some ice cubes and bitters (available from a liquor outlet) for a lovely evening drink, and/or some mint, borage flowers or citrus slices for decoration. You can use any mix of citrus: rangpur lime; lemon and limes; grapefruit and blood oranges; plain lemons. All are great but anything works.
2 cups zest & citrus juice of your choice
4 cups sugar
2 tbsp Epsom Salts
1 tbsp citric acid
1 tbsp tartaric acid
500ml of boiling water
1.5l cold water
Dissolve the sugar, Epsom salts, citric acid and tartaric acid in the boiling water. Add 1.5 litres cold water*, citrus juice and zest. Dilute to taste, usually about a quarter to a third with water or tonic water (I prefer soda stream).
*I cool the sugar syrup with the cold water before adding the citrus as some sources say heat can destroy vitamin C.
