Crumbly Butter Fudge

2lbs caster sugar (use brown sugar for a richer / darker colour)
1/4lb butter
1 cup of whole milk
400g tin of condensed milk
Teaspoon vanilla essence

• In a heavy based pan slowly melt sugar, milk and butter. Please be careful as sugar will be very hot.
• Once it comes to the boil add the condensed milk.
• Slowly bring to the boil again, stirring constantly.
• Still stirring carefully, boil for 15 minutes or until mixture darkens to a butterscotch colour.  (This can take much longer in some cases – no idea why)
• To test if mixture has boiled for long enough drop a teaspoon full into a glass of cold water.  If it’s ready it will form a ball.
• Remove from heat and add vanilla essence.
• Beat until your arm nearly falls off and the mixture has thickened to a very thick custard-like state (approx. 15 mins).
• Pour into a greased tin and cool.
• Cut into squares.  Store in an airtight container
