Hi all, been lurking here a while but first time posting, I've been busy reading through years of old threads.
Our freezer has an ice maker so storage space is pretty pathetic. I use the small resealable freezer bags from ASDA, less than a couple of quid for 40 i think.
I measure out 300ml portions of base in a measuring jug and pour into the bags. I try to get as much air out as i can without messing about too much. The bags lie flat in a shoe box that fits two side by side perfectly then each layer is separated with a piece of paper to stop them sticking together and tearing. Putting them in a box means i can stack other stuff on top to save on space.
To thaw them out i run the bag under the hot tap for a few seconds to loosen the block then snap it into smaller bits and tip into a bowl to zap in the microwave.
I think i usually get about 7 litres of single portions in the box, it's like a huge block of ice and no space is taken up by air or plastic cartons. Any leftover base gets used straight away or frozen in 4 portion batches.
