To make these you need:
125ml single cream
400g white chocolate (good quality, not eating choc)
2 Tbsp limoncello
Grate lemon zest (just remember to pick up a zest grater or you’ll end up using a food processor attachment, which takes a while, and is somewhat painful).
Put cream and zest into a small saucepan and bring to a gentle boil.
Remove from heat and strain into a medium (microwaveable) mixing bowl to remove the zest.
Add white choc and mix well until completely melted and smooth. You will probably need 2 or 3 short bursts (20s) in the microwave to help melt the chocolate.
Once cream and choc mixture is smooth, and limoncello and mix well
Cover and refrigerate for approximately 8 hours until mixture is set. Roll teaspoonfuls of mixture into balls and store in fridge until ready to coat.
Coat with melted white choc and leave to set
