Jamie Oliver's cunning kitchen hack will change the way you cook

We do love it when top chefs share their personal tricks and tips for cooking our favourite dishes - and Jamie Oliver has come up with a real gem.

The father-of-five took to his Instagram page to post his recipe for prawn and tuna linguine (who'd have thought of combining those two ingredients?) and gave us a top tip for the pasta sauce.

Jamie wrote: "Inspired by my time cooking with Nonna Rosanna, this prawn & tuna linguine is an absolute joy." He continued: "I’m using her trick of washing sliced onions to make them milder, and that moisture also helps to add extra sweetness as they cook!"
