Grilled watermelon, aubergine, chocolate crumbs, cucumber and ginger sorbet

Not yet rated

Andrea Berton highlights the versatility of the humble aubergine in this inspiring dessert recipe. He pairs the earthy notes of the vegetable with a refreshing cucumber and ginger sorbet that brings a delightful lightness to the dessert and pairs beautifully with the sweet nuances of the mint-infused watermelon. The chef also uses an exclusive pepper from Camo in Piedmont, however it can be easily substituted for the more readily available Sarawak pepper.
