Non-alcoholic cosmopolitan-style drink

1. Place a magnet in a large glass beaker, measure in 70% of the required water and put on a stirrer at 250-300rpm. In a separate jug, measure the additional water and put to one side.
2. Weigh the acids and stevia on to individual weighing boats and add to the water one at a time, starting with the citric acid.
3. Next, weigh the flavours in to individual weighing boats and pour them in to the beaker, rinsing them with the additional water to ensure completely added.
4. Weigh the cranberry juice concentrate in to a small beaker and, once the stevia has fully dissolved, add to the mix. Use the remaining water to ensure all the juice concentrate has been added.
5. Leave to mix for 3-4 minutes then decant in to 250ml bottles. Pasteurise at 75°C for 20 minutes then refrigerate for extended shelf life.
6. Shake over ice and decorate with a slice of lime and fresh cranberries (if available).

Note: Replace some of the water with soda water for a sparkling alternative.
