Ingredients
- 500g strong white bread flour
- 1 (7g) sachet fast-action dried yeast
- 10g sea salt, plus extra for sprinkling
- 4 tbsp extra-virgin olive oil, plus a little extra
- 1 small leek, white part only, sliced
- ½ tbsp olive oil, plus 1 tsp
- 100g baby potatoes, sliced 1-2 mm thick
- 75g extra-mature cheddar, in 1 cm cubes
Method
Step 1
Put the flour in a large bowl with the yeast on one side and the salt on the other. Add 400ml lukewarm water and 2 tbsp extra-virgin olive oil; mix with a spatula to form a sticky dough. Cover with a clean, damp tea towel and leave to rest in a warm place for 30 mins.Step 2
Scoop a wet hand under the dough and stretch it vertically until you feel some resistance, then fold it over itself. Rotate the bowl 90º and repeat this ‘stretch-and-fold’ motion – do this twice more, rotating the bowl 90º prior to each motion. This counts as one set of stretch-and-folds. Repeat the process twice more, leaving a 30 min gap between each set. After the third and final set of stretch-and-folds, leave to prove for a further 30 mins, until puffy and smooth with a slight jiggle.Step 3
Line a 33 cm x 22 cm baking tin with baking paper; drizzle with 1 tbsp extra-virgin olive oil. Tip the dough into the centre, then flip it over so the smoother surface is on top. Rest, covered, for 5 mins. Using oiled fingers, spread it towards the edges of the tin. Cover; leave to prove for 45 mins or until well risen and puffy.Step 4
For the topping, fry the leek in ½ tbsp olive oil over medium heat, stirring, until softened; cool. Toss the potato with 1 tsp olive oil.Step 5
Drizzle the dough with the remaining 1 tbsp extra-virgin olive oil, then prod all over with oiled fingers, leaving dimples. Rest for 15 mins.Step 6
Preheat the oven to 230°C/ 210°C fan/gas 8. Put a metal tray at the bottom.Step 7
Take your time arranging the toppings over the dough, stuffing the leeks and cheese into the dimples and placing the potatoes on top; sprinkle with sea salt. Pour a mugful of water into the preheated tray; bake the focaccia on the middle shelf for 25-30 mins. Transfer to a wire rack. Best devoured with friends the same day.
