First, pop the butter, Tate & Lyle Fairtrade Golden Caster Sugar and water in a pan over a gentle heat. Keep stirring all the time, until the butter melts.

Then add the smooth warmth of Lyle's deliciously sticky Golden Syrup and keep stirring over the heat until the sugar melts.

Stir continuously and then bring the sticky mixture back to a gentle boil.

To test your mixture, start by dropping just a tiny bit into a small bowl of ice-cold water. If it immediately hardens, you're ready to add the peanuts. If it doesn’t, continue to boil and then repeat the test again.

Pop in the peanuts and continue to stir. The little nuts will cool the syrup a little, so test it again in more ice-cold water. You’ll know that it’s ready when the brittle mixture hardens immediately in the water.

Next, carefully pour the mixture onto a lightly greased baking tray and leave to harden for about 30 minutes or so.

And finally – the most fun part! Smash the brittle into pieces with a toffee hammer or with the handle of a heavy knife.
