Thanks Jo. That's an awful lot of different soft drink sites!

We do have a lime/lemon soft drink that I could substitute for 7up, and we have a yellow and a red creaming soda. The red is a raspberry I think, but I don't know about the yellow one. Maybe I could use lemonade instead?

Now I have to find out how many fluid ozs are in the cans or bottles that Lor's recipes use, so I can convert this to mls.
