Put the dough ingredients together in the biggest bowl (seriously, the biggest) that you have
Mix everything together well
Leave to rise covered with a cloth for 4 to 5 hours
Make the topping (close to when your 5 hours are up!) by frying your sliced onions in a little Olive Oil over a low heat for 15 or 20 minutes or so – don’t let them colour too much. Then add 1 tsp vinegar and 1 tbsp sugar and cook gently for another 5 minutes – your onions will be sweet and soft and have a little tang too
Pre-heat your oven to 220˚c
Knock (or squash) the dough back into place and place it on a large and oiled baking tray. The dough should be 2.5cm thick once settled in the tray – I used a tin around 35cm by 20cm… play it by ear; am not sure it will matter too much
Decorate the dough with cooked Onions, Anchovies (from a can is fine) and halved Cherry Tomatoes. Drizzle with a tiny bit of Olive Oil and some Black Pepper (anchovies mean you don’t need extra Salt)
Bake for 20 or 25 minutes… Eat hot or warm with a big salad. This makes an excellent starter too
