Cookbook:Rosemary and Citrus Cordial

This recipe for rosemary and citrus cordial is adapted from page 26 of the April 2023 edition of Tesco's magazine.

Ingredients

 * 1 red grapefruit, scrubbed
 * 3 lemons, scrubbed
 * ¼ cup (20 g/0.7 oz) rosemary
 * 6 cm piece ginger, sliced thinly
 * ⅔ cup (150 g) superfine sugar
 * 1 cup (250 ml/8.5 fl oz) water
 * Fizzy water (optional)
 * Whiskey (optional)

Procedure

 * 1) Using a peeler, remove long strips of peel from grapefruit and 2 of lemons. Be careful not to remove any of white pith.
 * 2) Put the peels into a saucepan. Juice the lemons and grapefruit, and add the juice to the pan.
 * 3) Using a rolling pin, roll over the rosemary sprigs a few times on a chopping board to release the oils.
 * 4) Add the rosemary to the pan with ginger, sugar, and water.
 * 5) Heat for 5 minutes over a low-medium heat, stirring occasionally, to dissolve the sugar.
 * 6) Reduce the heat to low and cook for 15 minutes until you get a slightly thick syrup. Leave it to cool, then use immediately or chill overnight to develop the flavors.
 * 7) Strain the cordial syrup through a sieve into a bowl or jug. Transfer to a bottle.
 * 8) To use, mix 1–2 tablespoons of cordial into ⅔ cup (160 ml) of fizzy water to make a soda, or add to boiling water with 2 tablespoons of whiskey to make a hot toddy.
