@coriander I'll admit I couldn't find actual saccharine tablets.

Turns out saccharine tabs came in different sizes anyway, and the recipe doesn't specify.

But Sweet & Low has a lot of saccharine in it, so I decided that one packet of S&L counted as one saccharine tab. (That would be about right if he was using 0.5gr tablets.)

I think I guessed right. The sweetness was about right. That wasn't one of the problems.
