Rhubarb-Flan Tarts
This is a riff on Jean-Georges’s grandmother’s rhubarb tart. It’s not her recipe for the pastry or the streusel, but the notion of macerating the rhubarb before baking and adding the flan came from her. Mustard may not be a traditional ingredient for desserts, but it adds a definite edge to the jam and it’s my nod to Alsace, from where Jean-Georges hails. You’ll have leftover jam. Try pairing it with cheese or with a sizzling steak.
