Ingredients
Method
1.Lightly oil a large, lipped metal baking tray around 45cm x 32cm.
2.Place the sugars, water and butter in a pan and heat, stirring as little as possible, until the mixture reaches 140°C on your candy thermometer.
3.When the toffee has reached the correct temperature, remove from heat and carefully, but quickly, stir in the vanilla and baking soda (it will bubble up a bit). Pour into the prepared tray and tilt so it spreads evenly.
4.Quickly sprinkle the chopped pistachios and almonds and silver pearls over the top. Gently press into the surface with a palette knife or the back of a large spoon – be careful, it will be hot. Leave to set and cool.
5.When toffee has cooled, carefully lift it off tray and turn over.
6.Fill a medium saucepan with a 4-5cm depth of water and bring to a simmer over medium heat. Place the chocolate in a bowl over the water to melt. Stir until smooth. (I’m always looking for faster alternatives, so sometimes I melt the chocolate in the microwave at half power for 1 minute, stir and then heat for another minute, or until melted.)
7.With a pastry brush, paint a thin layer of melted chocolate over the underside of toffee. Leave to set then break toffee into shards and place in sealed bags or store in an airtight container.
