Pistachio Cake With Mascarpone Lemon Curd

This deeply moist and soft cake is scented with pistachios and sweetened with honey. A nutty cake needs something to offset its deepness, and a smothering of mascarpone and lemon curd does the trick quite nicely.
Note: To make a double layered cake as pictured, double the cake recipe, and divide the batter between two cake tins before baking.
