Plum tart

This plum tart is another great end to a dinner party. It's simple. It's elegant. It celebrates summer. The crust/topping is just a mix of flour, finely chopped walnuts, light brown sugar, butter, and an egg yolk. The filling is just ripe Italian plums which have been pitted and quartered and complemented with a bit of orange zest and juice. Best served warm, the only thing this tart needs is a scoop of vanilla ice cream. Wonderful...
