The lemon meringue pie filling was made by Greens - I believe it is still available, but don't quote me on that.
Anyone remember Foster Clarkes soups? They were solid blocks, that you crumbled into boiling water - the original instant cup-a-soup! They were scored, so that they could be broken into, I think, 4 pieces, with the remainder being re-wrapped for later use. As far as I can recall, there were only three flavours available - tomato, oxtail and something else, which I can't remember now - chicken maybe? Very handy for adding to stews, casseroles, and pies.
