Boyfriend made ‘Lethal Caffeine Laced Brownies’ last night, having discovered caffeine powder. He left my friend and I some this morning, with this stern warning note attached.
Update: He just emailed to tell us they are actually 4 to 6 shots per brownie, not 2 to 4 as previously estimated. We are pinging off the walls.
He also distributed them round his office, with the following email:
—————————————————————————————————
Morning all,
I’ve been baking again and of course I want to share, however, this’ll
be the first of my experiments that comes with a SERIOUS HEALTH
WARNING, aside from potential allergies - nuts, dairy and eggs btw -
they’ll be the least of your worries:
Firstly: If you have any heart conditions, or if there is history of
heart issues in your family, or you take the drugs fluvoxamine or
levofloxacin or derivatives -THEN YOU MUST NOT TRY THESE: THEY COULD
KILL YOU-
========================================================
Each square of brownie has 250-350mg of caffeine, thats 3-4 espressos!
========================================================
I really cannot express enough just how careful you need to be with
these! Unless you have very high tolorence then you should not have
more than 1, and you must not have more than one in any 4 hour period
-to a maximum of just 2 a day!-
Also, caffeine and cocoa are naturally bitter compounds, and despite
the additions of sugar, butter, egg yolk, raspberries, milk, apple
sauce, and walnuts that taste is still there, not unpleasant, like a
mild coffee level, but noticeable and I thought I’d warn you; tbh it
helps by stopping you eating more than one, and quickly, in any one
sitting, which (and I’ll state it again) you must not do!
So bottom line (esp you Carles!): try a half, if you like it, then
finish it off (or better yet, save it for later). Then -wait!-, in the
next hour you will start to feel -very- alert! Your heart rate -will
increase!- Do not have another brownie for at least 4 hours! Just
don’t do it! Don’t be macho, no dares, it isn’t worth it!
Eating 22 brownies would kill 1/2 of you (based on the estimated LD50
of caffeine). However as little as 2g -about 5 brownies- may lead to
serious complications, potentially requiring hospitalisation!
-So- if you understand the risks, as stated above, then please find
them after lunch in the waiting area under a bowl with this warning!
From this point onwards you eat them at your own risk!
