Vegetabel stock from scraps

I stumbled upon this brilliant idea a couple of weeks ago. It is quite simple:
1. Collect your veggie scraps in a container in the freezer.
2. Cook the veggie scraps with herbs in water for about an hour.
3. Drain. Use the stock.

This site has a useful picture to show which vegetables make good stock and what should be avoided.

Whenever the containers containing veggie scraps begin to take up too much space in my freezer I make a pot of stock (or rather I assume this is what I will continue doing, thus far it has only happened once) and make a soup with the stock.

So easy!
