This baked fruit dessert is a combination of berries, lemon zest and sugar with nut cream. Previously in Tuesdays with Dorie we've seen almond cream in tarts. In this berry gratin there is no tart shell, only the berries and the cream. Pistachios are used instead of almonds, with wonderful results.
It won't be berry season where I live for a couple of months, so I used frozen blueberries. The dessert would have tasted better with fresh berries. Lemon, blueberry, and pistachio are three flavours that I love, the the combination was delightful.
