I've used Luscome Sicilian Lemonade here, which uses an old-fashioned recipe. If you have people coming to dinner who are driving, then this mocktail is just the ticket.
If you can't find logan- or tayberries, there are some great early-cultivated blackberries which I'm pretty sure have been crossed with loganberries, so similar are they in look and a taste.
200g loganberries or tayberries
1ltr Luscome Sicilian Lemonade
A handful of bush basil
Crush the loganberries a little, then simply spoon into a tall glass with ice and a few sprigs of basil – top up with the lemonade.Reuse content
