In a saucepan over the grill add the water, honey, and mint. Stir to combine then leave to simmer.
Lemonade
Cut each lemon slightly off center, then cut a lemon slice from the larger side. When finished you will have two equally sized lemon ‘halves’ and a lemon slice. Continue this for all the lemons.
Place the sugar in a shallow bowl, dip each lemon half face down in the sugar then place it on the grill. Continue cooking until there are pleasant grill marks.
Tip the residual sugar into the simple syrup and stir to dissolve.
Juice all the lemons then pour the liquid into a large serving jug or similar.
Add the simple syrup to the lemon juice.
Add the 4 cups of water and ice, then stir to combine.
Three or four juiced lemon halves can be added to the jug.
To Serve
Pour a glass of lemonade, add extra ice, then garnish with the lemon slice created above when cutting the lemons (this can be grilled or not) and a small sprig of mint.
