Big Cubes


If you like the occasional cocktail, get yourself some really big ice cubes. They tend to melt slower and, thus, water your drink down less while also providing a nice big chunk of cold.


Better yet, a very large cube of ice will not act as a dam against the side of the glass like a typical ice maker “cube”.

An upgrade over 2″ cubes would be to create 2″+ spheres. Currently, there seem to be two products on the market to do this. Instead of rehashing information, I’ll just post a link to this fantastic weblog with an article that focuses on spherical ice making.

As @dnanian reminded me, there is this absolutely fantastic spherical ice cube mold out of Japan.   Beautiful piece of work, but both a bit spend and not exactly convenient.

Still… that mechanical engineering is quite drool worthy.

    At first, I was thinking “wtf? size doesn’t matter” (haha, she said). The ice cubes will absorb a certain amount of heat from the liquid, and turn into water. Doesn’t matter whether the cube is large or small.

    But then I thought some more… say the core of the cube is 20F. That core will keep the edges below 32F, even while the whole cube is stealing heat from the drink. Sure, the heat transmission through the cube will heat the core to (say) 25F, but that’s still *ice* rather than water.

    I would say the real goal is to get ice cubes as cold as freakin’ possible. Then to minimize the surface distance from the cold core (ie. spherical “cubes”).

    I’m not sure what the “negative” temperature density is for ice. But imagine soaking those babies in liquid nitrogen. Putting an ice cube at -346F into your drink… It is going to absorb a freak-ton of heat before melting.

    Short of the liquid nitro solution, it would be interesting to see if there are freezers that go below the typical -10F. Maybe some kind of industrial sucker that can make awesome anti-melting ice cubes 🙂

    I’ve been using the moma mould – works great.

    A while back I got these spherical ice molds: . I’ve been very pleased with them, and they’re a bit more economical than that (admittedly very impressive) Japanese spherical mold.
