300g strong bread flour
1 tsp fast action yeast
1 tsp salt
1 tbsp olive oil
150g smoked streaky bacon, cut into matchsticks (I used the whole pack)
4 tbsp creme fraiche
1 large onion, halved and sliced
50g gruyere finely grated
Put the flour in a bowl with the yeast and salt. Mix the olive oil with 200ml of warm water. Mix to a soft dough then tip onto a floured surface and knead for 5 minutes until smooth and elastic.
Cover with cling film and leave until you have made the toppings.
Heat a frying pan and add the bacon and a knob of butter. Fry for 5 minutes then scoop out and add the onions. Cook the onions until soft and golden.
Heat the oven to 230ºC. Divide the dough into 2 then roll each to a very thin oval and put each on a floured baking tray.
