Coconut, lychee and rose petals may seem like an unlikely pairing for oysters in a half shell, but you'll be surprised. Lychee are a perfect accent for oysters in a half shell, with their delicate texture and tart sweetness. Oysters share a citrusy, vegetal-mushroom aromatic link to these fragrant Chinese fruits, which are also prized for their lovely floral, rose scent. Just finish with a drizzle of coconut crème and a rose petal or two.
