- Preheat the oven to 180C. Lightly butter a 6-hole friand pan.
- Mix all the dry ingredients together. Add the melted butter and stir until combined.
- Whisk the egg whites with a fork. Fold into the butter mixture until well mixed. Pour the mixture into the friand holes to 2/3 full. Place a slice of tamarillo on the top of each.
- Bake for 20-25 minutes, until firm to the touch. Run a knife around the edge and tip out while still hot. These friands are best eaten within 24 hours but also freeze well. Serve warm or at room temperature.
