Use a silicone donut mould for easy release
Into each donut cavity, add 3 raspberries, 3 cranberries, and 2 mini rosemary sprigs
Pour freshly squeezed orange juice into each donut mould, filling to the top
Freeze for 6 hours or overnight until completely solid
Add 1 ice donut to a glass and pour The London Essence Blood Orange & Elderflower Tonic Water over the top
Watch the colours swirl as it infuses
