Grease a non-stick baking tray with sunflower oil. Drain the apples, dry each apple thoroughly and set aside.
Boil the rest of the ingredients over a low heat till ‘hard crack’ stage. If you have a sugar thermometer, the syrup should reach 150°C. If, like me, you don’t have one, it’s not the end of the world. Simply boil the syrup for about 20 minutes. Drop a bit of the syrup in cold water – if it sets rock hard straight away and is easy to crack, it’s ready.
Remove from the heat and as soon as the syrup stops bubbling, you can start dipping. Simply hold an apple by its stem and dip it in the syrup. I tilt the pan slightly to make this easier. But BEWARE, this syrup is ferociously hot, so it really is best to ignore phones, kids, dogs and nagging husband until you’re done.
Dip the syrupy apple in a small bowl of cold water (literally for one second) and place on the greased baking tray. Repeat with the rest of the apples. Eat immediately. If you keep them till the next day, the hard sugar coating will start to sweat – and sweat is never pretty!
