I use a thermomix for a quick mix. Place the water and warm it to 70°C, then add the yeast and mix. Leave it to stand for 5 minutes until the mixture froths.
Add the sugar, egg, milk powder, oil, and 350g of the flour. Set it to knead mode for 2 minutes.
Add the salt and knead for another 5 minutes.
Add the rest of the 150g flour and knead for 3 more minutes. Dough is ready.
I neaten the surface and put a coat of oil and return the dough to the machine, close and use the dough when it has risen and doubled. Normally less than 30 minutes.
