Pour the sugar into a heavy bottom saucepan, place on a medium heat and be BRAVE! Cook the sugar for a few minutes and it will begin to clump before turning silvery.
Swill the sugar around in the pan as it begins to melt, to ensure that all of the clumps are melted. No need to stir or use any utensils at all. The sugar will just stick to them and create a mess if you do.
Once the sugar has melted and gone past the silver stage it will look like it is burning. But that is just right. Once the sugar is a dark brown colour, like mahogany wood then add the peanuts. Mix together and the 'cooking' is done!
Leave to set in a 23cm baking tray lined with baking tray liners. I placed this in the fridge for 1-2 hours.
