Pre heat oven to 180°C \ 260°F and make rich short crust pastry to directions from my profile in my following recipes , or blind bake the pre made pie crust for 10-15 minutes or until lightly golden , remove from oven and set aside to cool while making the caramel filling .
In a heavy based saucepan place the milk and sugar and stir to combine , now place pan on low heat , cover and slowly bring to the boil - about 20 minutes . now with a wet pastry brush , brush the sugar crystals from the side of the pan , then add the butter , condensed milk and the golden syrup to the pan and through mixture is smooth .
Boil the mixture uncovered for 30 minutes or until it reaches soft ball stage - 115°C / 240°F on a sugar thermometer . Mixture should be a rich caramel colour .
Pour the mixture into the pre baked cooled pie crust , smooth out , cover with plastic wrap and put in the fridge to set for at least 2 hours , best overnight . Once set remove from fridge cut into portions and serve cold , can garnish with cream , ice cream , melted chocolate or just eat it the way it is . enjoy . :-) .
