Notes
RECIPE NOTES & TIPS:
Use good-quality dark chocolate – The better the chocolate, the richer the sauce! Cooking chocolate or a high-quality block of dark chocolate will give you a glossy, velvety finish.
Don’t rush the heating – Keep the heat at medium to low and stir continuously. Boiling too hard can cause the cream to split or the sugar to crystallise.
Add the Baileys last – Always stir in the Baileys off the heat. This keeps the flavour bold and stops the alcohol from evaporating.
Sterilise your jars or bottles – If you’re planning to gift your sauce or store it for the full month, sterilise your jars first to keep it fresh and safe to eat.
Storage is key – Keep the sauce in an airtight jar or sealed bottle in the fridge for up to 1 month. It will firm up in the fridge, so just warm what you need before serving.
Reheating without splitting – Pop some sauce into a microwave-safe bowl and heat in 30-second bursts, stirring in between, until warmed and smooth.
This one’s not freezer-friendly – Freezing changes the texture of cream-based sauces, and therefore it is unsuitable to freeze.
