Is their milk (I did watch the video) the kind which is hermetically sealed in a paper carton which keeps for a long time and doesn't need refrigeration? I have in the past kept some for when the weather forecasts were horrible (as in power going out). I've never heard of whipping cream (perhaps you call it double cream? It's something that one beats with a hand mixer to make a whipped topping for deserts.) being available in aseptic containers before?
Mushroom soup was quite good (if I do say so myself). I made it from scratch yesterday (adding in some cream today...see "What are you eating" thread if interested).
PD
No, long-term UHT milk mostly got popular in Southern Europe, but never up here; Denmark is an old dairy country, and we want our milk fresh, storing it in the fridge. UHT-milk is mainly bought as chocolate milk. Fresh milk is readily available even in the countryside in practically all of Europe now, but some of the people in the South seem to have a preference for it (and its taste); it is of course easier to store, if you live in a remote place, for example. The Danish add tells of milk coming from the cows into the shops in less than 24 hours, going of course through various processes on the way. "Arla Express" refers to the main dairy company and the express quality, of course.
I hope my translation was correct: whipped cream; I just mean ordinary, fat, fresh cream, that you make into that light, white substance yourself, like on the photo below. One doesn't normally add anything to the cream to make it. One can also buy it already made, in a can, where you can 'spray' it on your dish or drink, but the taste and density of that tends to be slightly different, IMO, it might even have added sugar.
Sounds great with homemade mushroom soup !
