Picnics are absolute proof that eating outside makes everything taste better. Find a shady spot, spread out a rug and lay out a feast for everyone to tuck in. Make it simple with lots of fresh sandwiches and a flask of cordial, so good when the sun is shining. Be more ambitious if you're out for a while, bring all the elements to compose salad plates, drizzle with dressing and slice lots of crusty bread to mop up the ends. Enjoy the delicate sparkle of elderflower champagne in the dappled shade and feast on fresh cake or chunks of fruit salad.
