Step by step recipe:

1. 5 min.
   Pour 200 ml milk, 150 ml water, 9 g salt, 15 g caster sugar and 50 ml olive oil into a pan, and warm over gentle heat.
   
   You can also melt all these ingredients in a bowl in the microwave for 1 minute.
2. 3 min.
   Tip 500 g flour and 20 g yeast into the bowl of a food processor, then add the warmed liquid.
3. 6 min.
   Knead on minimum speed for 5 to 8 minutes, until the dough is evenly mixed and elastic.
   
   Note: For the best way to knead, see: A few tips for effective kneading at home.
4. 5 min.
   Tip out onto the worktop without flour, and stretch...
5. 5 min.
   ... then fold back on itself a number of times.
   
   You can see how to do this in the recipe for leavened bread which has videos showing the movement.
6. 2 hours
   Next place the dough in a bowl, cover with a plastic sheet, and leave in a warm place until doubled in volume, which will take 2-3 hours.
7. 5 min.
   After this time, tip the dough out onto the worktop, press to expell the CO₂ gas that has formed, and shape into a ball.
8. 10 min.
   Cut the ball of dough into smaller pieces of about 50 g.
9. 10 min.
   Then roll each piece under your hand to make a nice ball and place on a baking sheet, as shown in this short video.
   
   You will see that you should try to keep both thumb and little finger straight (these roll the ball), and the other 3 fingers curved over the top.
10. 5 min.
    The dough is very sticky, which is quite normal, but means that they risk sticking to the plastic sheet when covered again.
    
    This little trick will help to avoid this: place a glass in the middle of each sheet between the rolls...
11. 2 min.
    And lay the plastic sheet over the glasses, so that the dough does not stick to it.
12. 5 min.
    Leave the rolls to rise and double in volume for 1 or 2 hours in a warm place.
    
    Preheat oven to 180°C (360°F).
    
    Just before baking, brush the rolls with a little milk to help them brown.
13. 20 min.
    Cook for about 20 minutes until golden brown, then leave to cool on a wire rack.
