Double cream I have heard you can whip up and then freeze in portions, or churn to make butter (saw Jamie Oliver doing this on the telly). No idea re the other two though. Maybe someone else will be along in a minute.
Evaporated milk, condensed milk and double cream. I have about 100ml of the first two and 200 of the last left over from making kulfi. I'm fairly sure I have abundant kulfi now. Is there anything else I can do to use it up -or am I going to have to give in and eat the condensed milk with a spoon while pretending to cook the kids' tea?
