I am not a fan of cordial these days but I enjoyed it as a treat when I was a child. My favourite was raspberry. I did buy a bottle of diet raspberry a couple of summers back thinking it would be a change from plain water. However, I have only had one or two drinks of it and didn't like it much!
NEVER. Our family was strictly water, fresh juices or coffee, coffee and more coffee. Needless to say I've stuck with the water (but in truth prefer light sparkling mineral water) don't really drink juices and don't drink coffee. But I do drink lots of tea. It must be a cultural thing as having European parents, I certainly don't recall any of our family friends and relatives having cordial either.
