Wipe over the strawberries and hull them by removing leaves and stalks. Cut them in half and drop into a wide mouthed jar, Kilners work really well for this.
Add the lavender heads and don't be tempted to overdo it as lavender has a strong flavour and can get too medicinal if you use too much.
Pour in the gin (normal supermarket stuff is what you want here, not to expensive stuff)
Add the sugar, seal jar and give it a good shake.
Put in a cupboard and shake every day for a week to get the sugar to dissolve completely.
After a week the strawberries will have lost their colour and the liquid will be a gorgeous pink colour.
Strain the liquid through 2 layers of kitchen paper in a sieve and decant into a pretty bottle.
Serve ice cold as a shot or with ice and tonic water, fizz or lemonade.
