This is the fudge recipe I use. It costs about £1.20 for about a kilo - it's a kilo because I use a brownie tin to set it in as I don't have anything smaller. You really do need to put the work in, don't be tempted to shortcut and I'd suggest wrapping a tea towel around your hand to protect it.
INGREDIENTS
? 700g caster sugar
? 200ml milk
? 200ml cream
? 160g butter
? 2 tsp vanilla extract
METHOD
Pour the milk into a medium heavy-based saucepan (attach a sugar thermometer), and bring slowly to the boil. Add the sugar and butter.
While stirring continuously, heat slowly until the sugar dissolves and the butter melts. Bring to the boil, cover and boil for 2 minutes.
Uncover and continue to boil steadily, stirring occasionally, for 15-20 minutes, until the temperature reaches 116 °C.
Remove from the heat, stir in the vanilla extract and leave to cool for 5 minutes. (You can try different flavours at this point, although chocolate needs it to be a lot cooler)
Beat the fudge until it just begins to lose its gloss and is thick.
