The Spreadable Butter product was developed for the UK/Europe where fridges with butter conditioner don't exist.

Don't know if the product is available in the US - given the surfeit of Dairy products already sold in the US, I doubt it, or it would be very hard to find.

i've never seen it blended with water here, but they market "whipped butter" (infused with air) for the same purpose. i've tried it, and it tastes fine, but i don't find that it spreads any easier than regular butter at refrigerator temperatures.
