Four years ago, in dreary mid-April, Rebecca asked me what I wanted for my Birthday dinner. I'd been preparing for the question, and quickly pointed to a quirky recipe I'd found for Watermelon Chiffon Pie. The pie was a winner; light, airy, and fresh, with the undeniable, but subtle flavor of fresh watermelon. This oddly addictive pie balances a sweet buttery graham crust with an almost cucumber-like freshness in the fluffy pastel-pink filling. While I request it every April, the best flavor comes from using fresh-from-the-market local watermelon in the heat of summer.
