but I would be careful Loosie to cook only in the minimal amount of water (steam cooking) as any water will tend to leach the vitamins, minerals, chlorophyll, plus other nutrients from the vegetables if too much water is used.
I personally use about one inch or just two and a half centimeters of distilled water to steam-cook my broccoli and cauliflower etc, and then only in the minimal time: say about eight minutes at boiling point when the veggies are beginning to soften.
Then use the leftover water and add to your own homemade gravy.
Delicious.
