OK, so it probably isn't new to ordinary people, but it just occurred to me the other day that, instead of getting those microwave steam bags of frozen veg (which I love, I am much more likely to include veg with a meal if it just involves shoving a bag in the microwave for two minutes, lazy but true) I could make my own...
So, do I just chop up veg and stick it in freezer bags, then use it like the shop bought ones, or is there some kind of method (par-boiling? Piercing the bag? Adding water?)
Are there any other "convenience ingredients" I could pre-prepare? Those frozen chopped onions I see in shops - do I just chop onions then freeze them in portions? Then use them straight from the freezer like I would raw onion? How about frozen mash, is that just mash, frozen, or do you do something special to it? Any other ideas?
Do I remember rightly that you can freeze cake mix? Could I make my own fish fingers and freeze them?
