Bring a large pan of water to the boil and cook the beans for 3 mins until just tender. Remove to a bowl of ice-cold water using a slotted spoon to halt the cooking process.

Set the pan back on the heat, tip in the pasta and cook following pack instructions. Meanwhile, pop the beans out of their skins so you’re left with the bright green beans, and set aside. (This is optional, but the colour, texture and flavour is improved. Discard the skins.)

Heat a small, dry frying pan over a medium heat and fry the pancetta for 5-7 mins until crisp and golden. Drain the broad beans and add to the pancetta along with the lemon zest and mint. Squeeze over one of the lemon halves and season well. Cook for 1-2 mins to warm through, then remove from the heat.

Drain the pasta, reserving a mugful of the water, then return to the pan along with the pancetta and broad bean mixture, the ricotta and a few tablespoons of the reserved pasta cooking water. Mix together, adding more of the reserved water if needed to create a slightly glossy sauce. Divide the pasta between bowls, squeeze over the remaining lemon half and scatter with the parmesan, if you like.
