why can neither full cream nor half cream be whipped? that wasn't always the case. but for a few weeks/months now i just can't get the whipped cream right. besides, the old cream that was taken out of the range a few years ago was the best anyway - why is it no longer available? (can't remember the name, the packaging was blue with a cherry on the front)
