A Pithivier is a French pastry or pie with an almond frangipane filling, very similar in fact to a British Bakewell tart. Although it looks plain from the outside it contains a filling that is sticky, sweet, nutty and altogether delicious.
There are plenty of variations on the recipe both sweet and savoury, my own twist was to add peaches both for colour and to cut the richness of the frangipane. I was slightly worried that the juice from the peaches would turn my pastry into a soggy mess but I needn't have worried. The peaches worked brilliantly with the almond filling, my only regret is that I didn't add more!
I used this recipe by Wolfgang Puck as a guide, I simply added tinned sliced peaches (in the summer I would use fresh) in between layers of frangipane filling.
