so any ideas? the protean powder i usually buy from holland and barrats says that it needs to be consumed within 30 min's of mixing
Isn't that just because otherwise it would settle out of the liquid? So you would probably just end up with a solid lump of it at the bottom of the drink.
Whereas if its in cake / flapjack / other solid stuff it will stay where it is.
