• Pour the condensed milk into a microwave-proof bowl, break up the chocolate and put it on top of the milk.  
• Put it in the microwave for 30 second bursts, until the chocolate is melted. The time taken will vary according to the power of your microwave.

  Go slowly, as you only want to melt the chocolate, not boil the mixture.
• Stir the milk and chocolate together until smooth. Add the mincemeat and stir it in.
• Prepare a tray by lining it with parchment paper.

  (If you are making a half can of condensed milk batch of fudge, a regular takeaway tray is the ideal size! If making a larger batch, either use two trays, or a 7-8" (18-20 cm) square pan.) 
• Pour the fudge into the prepared tray, and smooth the top. Place in the fridge for at least four hours to set.
• Cut into squares; store the fudge in a covered container in the fridge.

To make on the hob

• Prepare your trays. Pour the condensed milk into a saucepan, and then break up the chocolate and put it on top of the milk.  
• Warm the pan on the lowest heat and once the chocolate starts to melt, keep stirring it. Do not leave the pan, as it can rapidly overheat. If this happens, the mixture will split, spoiling your fudge. 
• Once the chocolate is melted and well combined with the milk, add the mincemeat and stir it in well. 
• Pour the fudge into the tray. Smooth out and once cool pop into the fridge to set for 4 hours or overnight.
