Heat the oven to 160C/140C fan/gas 3. Butter and line a 20 x 20cm square baking tin. Tip the butter, golden syrup and sugar into a saucepan. Stir for 5 mins or until the butter has melted and the sugar has dissolved. Tip the remaining flapjack ingredients into a large bowl and pour in the butter mixture. Stir to combine. Spoon the mixture into the tin and press down with the back of a spoon. Bake for 35 mins. Leave in the tin to cool completely.
While cooling, make the candied peel. Cut the peel into thin matchsticks and put in a saucepan with the caster sugar and 50ml water. Simmer gently for 5 mins, then leave to cool.
Top the flapjacks with the candied peel and leave to cool. Cut the flapjack into nine squares to serve.
