I've never had much luck with guar gum and my husband has asked me not to
experiment with it any more =) You could
sub guar gum, but other parts of the recipe would likely have to be changed
as well.
Just a thought
experiment (covering the missing human part): If you were a
sub commander in charge of ICBMs and you learned your country was destroyed, and took the time to verify (days perhaps because you have no communication) and you are somewhat certain but not perfectly certain
as to who did the attack, and your state no longer supports life, and your head of state is gone, do you fire your weapons killing millions of innocent people?
