Nothing?s quite as luxurious as Heston Blumenthal?s millionaire?s shortbread
Millionaire?s shortbread is a mix of refinement and indulgence, but people tend to buy rather than make it. Having a recipe means you can push the envelope with the different elements. After all, fresh shortbread is delicious, and you can make the caramel-and-chocolate layers as thick or thin as you wish. Eat as a biscuit with tea, or serve as a dessert with ice cream.
For the shortbread
100g butter, softened
60g caster sugar
Pinch salt
3 egg yolks
250g flour
For the caramel
1 x 397g tin condensed milk
120g unsalted butter
120g demerara sugar
For the chocolate topping
100g milk chocolate (or plain ? depending on personal preference)
To make the shortbread, cream together the butter and sugar. Add the salt and egg yolks, then stir in the flour, using your hands to mix it thoroughly until a soft dough is formed. Wrap the dough in clingfilm and leave to rest in the refrigerator for at least 2 hours.
Line a baking tray (about 20cm x 24cm in size) with baking parchment. Once chilled, roll out the dough to a thickness of about 0.5cm and press into the prepared tray.
Chill in the refrigerator for a further hour. Meanwhile, preheat the oven to 160C/ 325F/Gas Mark 3. Bake the shortbread for about 20 minutes until golden brown. Remove from the oven and set aside to cool in the tin.
While the shortbread is cooking, you can tackle the caramel. Put the unopened tin of condensed milk in a saucepan and cover with water. Bring to the boil and simmer gently for 4 hours, being careful not to let it boil dry. Set aside to cool. Do not open the can while still warm.
Melt the butter in a small pan over a gentle heat, then stir in the demerara sugar. Leave to simmer until the sugar is completely dissolved. Whisk in the caramelised condensed milk until the mixture is completely smooth, then pour it over the cooled shortbread base. Spread out evenly, and set aside to cool completely.
Break the chocolate into a bowl, and place the bowl over a pan of boiling water. Stir until all the chocolate has melted. Pour the chocolate over the cooled caramel, smoothing it with the back of a knife. Put the tray in the refrigerator to allow the chocolate to set.
When you are ready to serve, cut the caramel block into your desired portion sizes and indulge.
