Pick some ripe citrus fruits
Squeeze your 2 ruby grapefruits and 1 of the lemons through a sieve to prevent bits and pips going into your drink
Pour into a large jug filled with ice
Chop your orange and lemon for garnish. Add molasses sugar to taste, we like 1-2 dessert spoons. Stir very well.
Now top up with ginger ale, stir and serve
