Walnut tart is a classic in south-west France, especially the Dordogne. Recently some visitors arrived from the Lot with a big bag of freshly gathered walnuts, so I had to try making it. It looks a bit odd, but it’s delicious, like a very sophisticated version of treacle tart. I used the recipe from Geraldene Holt’s lovely book of traditional French cuisine, French Country Kitchen, which is no longer a neglected cookbook.
It’s well worth making the pastry with orange juice; it adds an extra zing. In light of this, I substituted Cointreau for the rum Geraldene uses in her filling, and that was a good idea too. Pro tip: it takes ages to shell enough fresh walnuts for this, but listen to something nice on the radio while you do it 🙂
