Boil the sweet potato cubes in water for 10 minutes. Drain thoroughly.
300 g sweet potato
Mash the sweet potato and let it cool to room temperature.
Mix the 75ml water, yeast and coconut sugar together. The water should be around body temperature (i.e. if you touch it, it doesn’t feel hot or cold). Leave the mixture to froth for 10 minutes.
75 ml warm water, 7 g dried yeast, 1 tsp coconut sugar
Add the frothy yeast mixture and the cooled mashed potato to a large bowl and mix together.
Add the flour and salt to a separate bowl and stir until combined.
300 g strong white bread flour, 1 tsp salt
Add the flour mixture to the sweet potato mixture, a little at a time and stir it in until fully combined into a dough.
Knead your dough for 10 minutes until soft and smooth.
Put the dough in a lightly oiled bowl, cover it and leave it in a warm place to prove for one hour.
Roll the dough out to around 2 cm thick. Cut out or shape 8 rolls and place them on a lightly floured tray.
Cover the tray with a tea towel and leave in a warm place to prove for 30 minutes.
Pre-heat the oven to 200°C fan (220°C conventional / 425°F / gas mark 7).
Bake the rolls for around 15 minutes until golden on top and giving a hollow sound when you tap them on the base.
Enjoy warm or lightly toasted with avocado and chilli sauce.
