Tinned pineapple is acidic enough to take a hard caramel without going sickly, which is what makes this work where tinned peaches would not.
Dry the pineapple. Drain it, press the rings, then press again. Wet fruit will not caramelise; it will boil in its own juice and go grey.
- Almonds toasted dry in the pan, two minutes, tipped out.
- Same pan, hot, the oil. Pineapple rings in one layer. Three minutes untouched until the undersides are deep gold, then turn.
- Scatter the sugar over and let it melt and darken for a minute.
- Syrup in with two tablespoons of the reserved pineapple juice: it will bubble hard. Turn the rings through it until it goes sticky.
- Cinnamon, almonds over.
Serve with tinned custard or evaporated milk poured cold over the hot fruit, which is better than it sounds.
Serves 2.
