Def Leppard and sugar cubes; two great tastes that taste great together.
Dark lumps or light?
Once upon a time, sugar came in cubes or not cubes, brown or white. Now there are wondrous selections of accoutrements for your tea or coffee. Enough to suit any sweet tooth! It really is a wonderful world.
I'm not sure I'd want to give a pack of kids handfuls of straight sugar as a snack but I could see these set out for coffee with the ladies.
