Clear as ice.

 

Ok, time to ice-splain

This is a wall of text but extremely easy to accomplish. Refrigerator ice comes out very white, but if you look closely it is very clear around the edges and white in the center. Refrigerator ice freezes from the outside in.

The white bits are all the impurities in the water, those impurities freeze LAST. The trick is to control the direction that the ice freezes, this process is called, simply, directional freezing. There are a lot of ways to do this, but this ice tray from amazon is the easiest.

How does it work?

The tray insulates the tray on 5 of the 6 sides with styrofoam. The 6th side, the top, is the only exposed part of the water, therefor it will freeze first. All the impurities (the white bits) will be forced downwards into the water reservoir below. When complete and you separate the silicon mold at the top, those cubes will all be uniform in size and perfectly clear (they may have some frost right on the top surface, but if you let the cubes stand alone in a room for 5 minutes they will clear up).

Why clear ice?

1. it looks bad ass
2. it tastes better since all the impurities are removed, they will not get into your drink and foul up the taste
3. it will stay colder for a longer amount of time.

The level of effort is stupid-easy. The hardest thing you are going to do is pour water. Everything else is just time and patience.If you want a science experiment you can try it in a very small batch. Get a metal yeti/stanley/tervis tumbler. It will need to be one of the slightly conical ones (with perfectly straight 90degree angles you will never get the ice out)

1. Fill the tumbler 90% full of water and put it upright in your freezer without a lid.
2. Let it freeze for 18-20 hours.
3. Take the tumbler out and set it on the counter for at least an hour.
1. it needs to thaw just a tiny amount otherwise the tumbler will not let the ice out of the vessel.
4. After an hour the ice cylinder should slide out (do this over a sink, there will be very cold water involved) If it doesnt want to come out give it a little more time. The cylinder will be half clear and half VERY white.
5. You can chip away the white puts with an ice pick or cut it away with a serrated bread knife.

This won't make a lot at one time, but if you only have one cocktail a week, it is an easy way to accomplish the task.
