I got this reipe through a friend on FB, it sounds delicious. I still have lavender in the garden so shall make some.

1 pint water
1 oz lavender flowers
8 oz sugar
Juice of 4 lemons

Pour boiling water over the lavender flowers and allow to infuse for about 20 minutes. Then add sugar and lemon juice, and chill. Store in the ‘fridge.To make up, mix about 1 part of the syrup to 4 parts water, serve with ice.
