Tomato Water is when you take some ripe tomatoes, cut them up, and then put them in a blender or food processor and liquefy them. Then, you line a colander with coffee filters or paper towels. Next, get a large bowl and place a wire rack on top of it. Put the lined colander on the rack so that it is over the bowl.
Now, pour the liquefied tomatoes into the colander and put the whole works in the fridge and let it sit over night. The juice slowly drains through the coffee filters and collects in the bowl beneath. And, believe it or not, it is clear! Looks like water, but taste strongly of tomatoes!
Really cool. I just learned about doing it the other day when I got so many tomatoes and had to figure out what to do with them.
Another plus to doing this is the pulp that is left over in the colander can be pressed through a sieve or run through a food mill to remove the seeds and skin leaving you with a really smooth and creamy tomato sauce or Tomato Coulis if you will. So, in deconstructing the tomato this way, you get two tomato products that you can use.
The tomato water can be used in all kinds of things including cocktails like a Bloody Mary or mixed with a shot of vodka.
The coulis is a great base for sauces.
