After that it was plain sailing, although I forgot to fold in the chocolate chunks and had to sprinkle them over the surface of the batter after it had been in the oven a few minutes. Fortunately, the bars seemed none the worse for this!
This recipe is reproduced with permission from the publishers, and I have included the metric weights I used, where appropriate:
10oz (300g) white chocolate, 50g chopped into chip-sized pieces
6 tablespoons (150g) butter
1/4 cup (50g) granulated sugar (I used caster sugar)
1/2 teaspoon salt
2 large eggs at room temperature
1 teaspoon vanilla extract
1 teaspoon vanilla bean paste
1 cup (130g) all purpose (plain) flour
1/2 cup (125g) lemon curd
Pre-heat the oven to 350F (180C) and line a 8" (20cm) square tin with baking parchment.
Melt the butter and 250g of the white chocolate together in a large bowl, over a pan of simmering water.
Remove the bowl from the heat and stir in the sugar and salt.
Whisk in the eggs, one at a time, then whisk in both the vanilla extract and bean paste.
Gently fold in the flour, followed by the chopped chocolate, and put the batter into the baking tin.
Dollop the lemon curd onto the batter in 5 or 6 equal portions, and swirl into the batter using a knife and a figure of 8 movement.
Bake for around 25 minutes, until a tester comes out clean.
Cool on a wire rack, then cut into 12 bars when completely cold.
My bars don't look perfect, because of sprinkling the chocolate chunks over the batter instead of folding them in. This caused little hollows to form as the larger chunks sank, although these hollows seemed to happen where lemon curd was left on the surface too.
This recipe is worth repeating just for the blondie base, if I can face the trauma of working with white chocolate again, perhaps with dark chocolate or fudge chips added, and Shauna also suggests replacing the lemon curd with any good quality low-sugar jam with a tart flavour, to ring the changes.
I'm so pleased my first recipe from this book was a success; it gives me confidence to tackle some of the more complicated recipes, and endorses my positive review of the book given from the first reading. Although I received a free copy of this book, I was not required to give a positive review of either the book, or the recipes I tried, in return.
