If Queen Elizabeth II has given something her seal of approval, you know it has to be good. That can definitely be said for Prestat’s fine candies, the official “royal chocolates” of the matriarch — and a sweet treat that was served at the Duke and Duchess of Cambridge‘s wedding. The heart-shaped artisan truffle box ($27) is a favorite — and a recent U.K. import — offering 12 different truffles like tropical cinnamon, Sicilian key lime, ginger fire and sweet sea salt. For more traditional sweet tooths, there are chocolate bars with hints of mint, cinnamon and more ($15 for three). Find the delicious delectables online at chelseamarketbasket.com.
