Ingredients
Method
1.Roast hazelnuts in a moderate oven, 180°C, 10 minutes. Cool, then rub together in a tea towel to remove skins.
2.Process hazelnuts in a food processor until ground. Place in a bowl; add sifted flour and spice, sugar and zest.
3.Add butter; rub in using fingertips until mixture begins to come together. Add egg yolks; mix to a dough using hands.
4.Turn dough onto a well-floured surface. Shape mixture into a ball. Wrap in plastic wrap; chill 1 hour.
5.Preheat oven to moderate, 180°C. Lightly grease a 23cm loose-bottomed flan pan.
6.Roll three-quarters dough between two sheets of baking paper until 3mm thick. Ease into pan. Trim edges (pastry is very “short” or crumbly, so just press crumbs back into pan); chill 10 minutes.
7.Meanwhile, lightly knead remaining pastry and trimmings together. Roll between two sheets of baking paper to a 10 x 25cm rectangle; chill 10 minutes. With a fluted pastry cutter, cut into 10 strips, each 1.5cm wide.
8.Spread jam over pastry case. Arrange 5 strips across the tart, then remaining strips across to form a lattice pattern.
9.Bake 35-40 minutes, until golden; cool in pan 10 minutes. Dust with icing sugar and serve in wedges with cream.
