How do you cook pufferfish?
You don't cook fugu, ie pufferfish. And it can be very dangerous to eat it raw.
Is puffer fish even sold in stores? I thought it was one of those specialty 'russian roulette' dishes in restaurants.
TTX (tetradotoxin) is a lethal neurotoxin produced by puffer fish, its a Sodium channel blocker which essentially prevents the muscle cells from contracting, thus paralysing the diapraghm which helps your lungs 'breathe'.
