for a ‘zero waste’ picnic, simple is best – a fresh baguette with some ham or cheese, a bag of cherry tomatoes, a cucumber and a punnet of big fat english strawberries. we like to shop in markets and prepare our own food to avoid too much packaging. we take glass jars crammed with mouth-watering marinated olives, feta and sun-dried tomatoes, individual bottles of homemade elderflower cordial (see our recipe) and paper straws to drink with, pack everything into a favourite woven basket and spread out our simple, rustic feast on a check rug with a stack of washable napkins.
