Insert the butterfly whisk into the Thermomix bowl. Add the cream and whip for 2-3 min/speed 3, with the measuring cup off. Timing varies depending on the quantity and freshness of the cream and how chilled it is.
After 30 seconds, watch the cream carefully through the lid to avoid over-whipping. If it’s close but not quite ready, stop and check the consistency, then mix again in 3-second increments until stiff peaks form.
Add the sweetened condensed milk and coffee essence and mix for 10 sec/speed 3. Scrape down the sides of the bowl with a spatula, then mix again for 10 sec/speed 3.
Transfer the mixture to a freezer-proof container and freeze for 6 hours before serving.
Notes
Coffee Essence: If you're in Australia, I recommend Bushells Coffee & Chicory Essence, which comes in a 250ml bottle. If you're in the UK, Camp Chicory & Coffee Essence is a great alternative - it looks very similar to Bushells. The quantity used might seem like a lot, but it helps balance the sweetness of the condensed milk.Storage: Store the coffee ice cream in an airtight container in the freezer. Cover the surface with grease-proof paper to minimise air exposure and maintain a smooth texture. It's best consumed within 2 weeks.
