How to make it
Divide custard evenly into 5 small ramekins. Level the top and place in the fridge.
Place water and sugar into a clean saucepan and allow to simmer for 10 to 15 minutes (do not stir) or until a light toffee colour is reached.
Allow toffee to cool slightly, then carefully pour a thin layer onto the chilled custard. Serve and enjoy!
Another method for the toffee topping is to sprinkle 1 teaspoon of caster sugar on top of each custard filled ramekin, then use a blowtorch to heat the sugar until it caramelises and forms a hard crust. Be careful not to burn the sugar as it can taste bitter.
