Brownie recipe:
225 grams dark chocolate (good quality dark cooking chocolate of your choice is fine. Don't use eating chocolate, it goes grainy when you melt it)
100 grams unsalted butter
225 grams caster sugar
2 whole medium eggs plus the yolk of a third egg
175 grams plain flour
0.5 teaspoon of baking powder
150 grams (shelled weight) of pistachio nuts (not chopped)
150 grams of dried apricot (cut into pistachio nut size pieces with kitchen scissors
Put the butter into a thick bottomed saucepan. Start melting over a very very low heat, breaking the chocolate into it. Stir until the chocolate is completely melted and the mixture is glossy.
Put the sugar in a mixing bowl, pour in the melted chocolate. A good silicone spatula is your friend. Stir the chocolate and the sugar together until well mixed into a slightly grainy mix. Add the eggs and yolk, stir in until well mixed. Add the flour in two or three dollops, stirring until all incorporated. The mixture should be shiny, quite thick and not too sticky. Add in the apricots and pistachio nuts.
Put the mixture into a square brownie tin lined with baking parchment (this is important because without the paper they will stick). Spread the mixture evenly - it should not stick to the spatula you are using at all.
Bake in an oven preheated to 160C (Fan, you can go 170 for non fan but no more!) for 35 minutes. Top of the brownie should show some light cracks, a skewer should come out mostly clean but there may be a little melted chocolate. Take it out and leave in tin to cool.
This recipe also works very well with 150 g dried cranberries and 150g toasted pine nuts.
