Ingredients:

• cashew nuts 300g
• caster sugar 300g
• butter 150g
• sea salt flakes

Instructions:

• Heat the oven to 180C/fan 160C/gas 4. Scatter the nuts onto a baking sheet and toast in the oven for 5-10 minutes, tossing regularly until brown, then spread evenly on a piece of baking paper on a large baking tray.
• Put the sugar, butter and 125ml water in a large pan and heat gently until melted. Turn up the heat until the mixture is bubbling, then leave to cook until it has turned a rich golden brown – this will take about 20 minutes, depending on the heat.
• Keep a close eye on the pan and give it a stir every now and then. Once the mixture is golden brown, remove from the heat and pour straight over the cashews.
• Sprinkle generously with sea salt flakes. Leave to set before breaking into shards and packaging it.
