Think about that first tickle of hunger in your stomach. A moment ago, you could have been thinking about anything, but now it's thickly buttered marmite toast, a frosty scoop of ice cream straight from the tub, some creamy, cheesy scrambled eggs or a fuzzy, perfectly-ripe peach. Eating is one of life's greatest pleasures. Food nourishes our bodies, helps us celebrate our successes (from a wedding cake to a post-night out kebab), cheers us up when we're down, introduces us to new cultures and — when we cook and eat together — connects us with the people we love.
