The Food Lab: My Favorite Cooking Hacks

I already covered their beer-cooler sous-vide hack. For the wok hack,

When filled part way with coals and allowed to ignite, the well-ventilated chimney channels all of that heat energy upwards.

True for the convection, which is the most important heat transfer going on. (But the radiation is still pedantically being emitted out the other sides.) And the ice-cream-without-an-ice-cream-maker sounds intriguing. I’ve had liquid nitrogen ice cream, which is a truly geeky hack that achieves the same goal of quick freezing so you get small crystals.
