Make the dough. Put all the ingredients except the extra melted butter into a large bowl and mix by hand or with a mixer until a soft, smooth and elastic dough forms. If you’re mixing by hand this could take up to 10 minutes, in a mixer it takes around 4-5 minutes.

Place the dough in a clean bowl, cover with a damp cloth and leave to rise in a warm place (somewhere that’s around 27°C/80°F is ideal) until doubled in size, about 90 minutes.

Turn the dough out onto a floured surface and gently press it down to remove any large air pockets (no need to flatten it into submission here!). Divide the dough into 15 pieces and form each into a smooth roll.

Place the rolls in a lightly greased or parchment-lined 22cm x 32cm (9in x 13in) pan. Cover the pan with a damp kitchen towel and let the rolls rise until they’re puffed and the dough springs back into shape when a finger is gently pressed onto the surface, about 60-90 minutes. Towards the end of the rising time, preheat your oven to 180°C/350°F.

Bake the rolls until they’re golden brown, 20 to 25 minutes, then remove from the oven and turn them onto a rack. If you’d like to give them a gloss, brush each roll with melted butter while hot.

Serve rolls warm or at room temperature. Store any leftovers in an airtight container for a couple of days at room temperature, or freeze for up to 2 months.

Place the dough in a clean bowl and use the dough proving setting in your steam oven until the dough has doubled in size, about 30-40 minutes. There’s no need to cover the bowl. If you don’t have a dough proving setting, steam setting at 35°C/95°F (100% humidity) will achieve similar results.

Turn the dough out onto a floured surface and gently press it down to remove any large air pockets (no need to flatten it into submission here!). Divide the dough into 16 pieces and form each into a smooth roll.

Place the rolls in a lightly greased or parchment-lined 22cm x 32cm (9in x 13in) pan. Place the pan in your steam oven on dough proving setting again and let the rolls rise until they’re puffed and the dough springs back into shape when a finger is gently pressed onto the surface, about 25-30 minutes.

With the pan still in the oven, change your oven temperature to 180°C/350°F, combination steam setting. If your oven has variable steam levels, select 30% humidity (if you don’t have variable steam settings, don’t worry! Just set the temperature and combination or convection steam, and the oven will work out the rest).
