Weigh your flour and water into a large bowl and whisk thoroughly until there are no lumps. Leave it to rest in a warm place for 4-6 hours and give it a whisk every couple of hours (or you can leave it to rest overnight).

Preheat your oven to 280°C.

Just before you are ready to cook the farinata, whisk in the salt.

Heat 1.5 tablespoons (a generous covering) of olive oil in an an oven proof frying pan over a medium heat. Slowly and carefully ladle in some of the batter, so that it floats on top of the oil rather than mixing in, until the batter is around / just under 1cm thick.

Add your rosemary and any other herbs you want to use, and bake in the oven until the top is a golden yellowish-brown in colour and has crisped up. If you struggle to get this finish in your oven, you can finish it off under the grill. Depending on the size of the frying pan you are using, repeat this if necessary until you’ve used up your batter.

Serve immediately, sliced into wedges. Season with salt and pepper if it needs it.

You can add other fillings to your farinata if you like, such as cheese (blue cheese or grated Parmesan is lovely), red onion, roasted garlic, or cooked vegetables such as thinly sliced baby artichokes or mushrooms and truffle oil.
