- 400g golden caster sugar
- 1 tin condensed milk
- 120g salted butter, chopped into pieces
- 1 tsp vanilla bean paste
- 3 tbsp amaretto (optional)
Put the sugar, condensed milk and butter in a LARGE heatproof bowl (the mixture is going to bubble to double its size), add a generous pinch of salt and stir together.
Microwave on high for 10 mins, stirring every 2-3 mins.
Add the vanilla and optional amaretto to the mixture, whisk together and heat on high for another 2 mins. The mixture should be caramel in colour and much thicker than when you started. Scrape into a greased and lined baking tin and set aside cool and firm before cutting (give it at least an hour). Pack into a gift bag and eat within 3 weeks.
