Grapefruit is the most refreshing and healthy food you can start your day with, and the star anise gives it a special aroma. The best way to grind the anise is with a spice or coffee grinder. If you don't have one, you will need to work hard with a pestle and mortar to break the anise down and then pass it through a fine sieve – that's your morning exercise sorted.
2 pink grapefruit
1 tsp ground star anise (about 4 stars)
3 tbsp demerara sugar
80g Greek yoghurt
1. Halve the grapefruit and shave a thin slice from the bottom of each half so that it sits flat and stable. Use a special grapefruit knife or another small and pointy serrated knife to cut in between all dividing membranes, so you can later spoon out the fleshy segments without difficulty.
2. Place the grapefruit halves on a baking tray, cut sides facing up. Sprinkle the star anise on top, then the sugar. Place under a very hot grill for 2-4 minutes, until the sugar melts and caramelises. Some domestic grills are not powerful enough to give you a real brulee effect. This doesn't matter; the melted sugar and anise will still taste great. (If you have a blowtorch you can use it once the fruit is out of the oven to help caramelise the sugar.)
3. Place the grapefruit halves on plates and serve with a generous dollop of yoghurt, on top or in a little dish or ramekin on the side.
