Aside from mixing some packs (chocolate + vanilla makes a nice shake), the so-called "cooking" with the packs is all a disaster as far as I've seen.
None of the recipies come out like you expect them to, and after a disgusting "muffin" and floppy "crisps" I gave up. The whole point of LL is to get AWAY from food, not to take your nutritional delivery systems and try to make them INTO food - it's our obsession with eating that drove us to need LL in the first place.
My 0.02cents anyway.
