Method · 45 min
  1. For the lemon and mint butter, whisk together all the ingredients in a bowl with a pinch of salt until combined
  2. Place the courgettes in a bowl with the olive oil, garlic, lemon juice and a pinch of salt. Toss to combine and set aside
  3. Set up a barbecue for direct grilling. Grill the courgettes until you’ve achieved bar marks all over – about 2-3 minutes each side – then remove and chop into bite-sized pieces. Set aside
  4. Bring a large saucepan of salted water to the boil and cook the rigatoni until al dente. Drain and reserve a cup of pasta water
  5. Meanwhile, fry the capers in the olive oil in a frying pan over a medium heat until they open slightly and become crispy. Remove with a slotted spoon onto kitchen paper to drain the excess oil
  6. Toss the hot pasta together with the butter and a splash of reserved pasta water (you can add less butter if you like, but include at least 100g of it). Stir until the butter emulsifies into a sauce, and then fold through the charred courgettes
  7. Divide the pasta between bowls and finish with the fried capers, Parmesan, mint leaves, a pinch of black pepper and a drizzle of olive oil

Much like fettuccine alfredo that was traditionally made by emulsifying butter, pasta water and cheese together to serve, this compound butter makes an instant sauce, which is topped with sharp and crunchy fried capers.
