Heard one of those tips that brought on a "Why didn't I think of that?" moment and so assumed there must be loads more like it out there. So I'll post it here if you'll all post similar in return. It is of course, purely for theoretical research Tip no. 1: Instead of slicing a fresh lemon for G&T (with inevitable result that 2 or 3 weeks later the remains of the lemon has transformed to a small furry creature lurking at the back of the fridge - Get 1 x lemon. Cut into slices. Freeze the slices. Every time you have a G&T (or anything else requiring lemon) drop in the frozen slice. Also cools the drink without diluting it; quality.
