A refreshing, sweetly herbal fizzy drink for the moment the lavender is at its most fragrant, just as the flowers are starting to open. Add a shot of gin for an adult version.

Makes 6 glasses

500ml water
200g caster sugar
10 lavender flower heads, plus more for decoration
12 lemons
fizzy water

1 Place the water, sugar and lavender flowers into a saucepan and heat gently until the sugar dissolves. Simmer very gently for ten minutes, before removing from the heat and leaving to cool completely. Transfer to a jug or jar, lavender flowers and all, and chill.

2 When you are ready to serve, squeeze the lemons into a jug, tip in the lavender syrup and top up with fizzy water, aiming for about a third of each ingredient. Serve over ice with a lavender stalk and a piece of lemon.
