It might not look like it, but the inspiration for this tart was the Bakewell tart. The first step in a gradual change was to add cocoa to the usual frangipane filling to make a chocolate version. After a while, I changed the jam used, because apricot seemed to be a better partner for the chocolate and almond combination than the traditional raspberry. That version, sometimes topped with flaked almonds, and sometimes with a glacé icing, has been a family favourite for many years, and has also helped to stock many fund-raising cake stalls, when made in small foil cases.
This time, I decided to use some of the foraged hazelnuts, instead of almonds, and to up the chocolate content by adding 100% cacao to the filling, as well as cocoa powder. This gave the filling extra richness and depth of flavour which contrasted well with the sweet, yet tart, apricot jam. I was fortunate that although my choice of jam (Aldi's own brand conserve) had quite a soft set, it contained large pieces of fruit which improved the texture.
We Should Cocoa challenge, which is to use jam and chocolate together. We Should Cocoa was the brainchild of Choclette, over at Chocolate Log Blog, and the rules for the challenge can be found on this link. Choclette alternates her hosting duties with guest hosts, but it is fitting that she should be the host for this month's challenge, as it is entering it's 5th year. I think that's a fine testament to the universal appeal of chocolate!
A loose-bottomed flan dish (about 20-22cm in diameter) lined with shortcrust pastry (no need to bake blind).
200g apricot jam
Filling: 60g ground hazelnuts, 40g SR flour, 100g caster sugar, 100g baking spread or softened butter, 1/2 teaspoon baking powder, 2 large eggs, 25g cocoa, 25g 100% cacao (finely grated), milk to mix.
To finish: 50g coarsely chopped hazelnuts, blanched if necessary.
Preheat the oven to 200C and put in a baking sheet to heat, too.
Spread the jam into the pastry case, and chill while making the filling.
Put all the filling ingredients, except the milk, into a bowl and beat with an electric mixer until the batter is well blended. Add a little milk, if necessary, to give a soft dropping consistency - you shouldn't need more than a couple of tablespoons.
Fold in half of the chopped hazelnuts, then spread the batter into the pastry case, being careful not to leave any gaps around the edge where the jam might bubble up during cooking. Scatter over the remaining hazelnuts.
Put the tart on the heated baking sheet and bake for 15 minutes, then lower the temperature to 180C and cook until the filling is firm - roughly another 30 minutes. Serve at room temperature.
