Yes. Mother made it all the time in England. We used to laugh and say it looked like frog spawn. (It really does.) Sago and tapioca are similar but sago is smaller "balls" where tapioca is more like pearls.
I have eaten this.....whenever I have been in hospital on a restricted diet. I must say that I am not at all fond of the texture,so whatever delicious sauce is served with it to add flavour,just never seems to turn it into a dish which does anything much for me. I would prefer to just have the sauce!! Hee Hee Hee!!!!
