Nice and easy: click on the logo of your favorite supermarket to add the ingredients.
And this is how you make it:
Place all ingredients for the syrup in a saucepan and bring to the boil. Let it cook slowly until the strawberries have given all their color to the syrup and the syrup has reduced a bit. Pour through a fine sieve into a glass bottle.
Put some ice in a GT glass and pour 30 ml syrup, 50 ml gin and 180 ml tonic per glass.
Garnish with the strawberry and basil tops and serve.
