"Oh, well if it's your family recipe, it must be good..." She says before taking the offered beaker and downing about a half a cup's worth. Well, this isn't so... The burning suddenly convulses her throat and she coughs a couple times. Then a couple more times. Then shakes her head as if to shake off the effects. Wow. She offers a weak smile as if to say I'm sure, Mr. Grounder, that this is the finest pure-death-in-a-bottle to be found in known space.
