Broccoli

If You Read Nothing Else

Steam for four or five minutes. Boiling washes out the useful part and kills the enzyme that makes it.

Chop it and let it stand ten minutes before heat. That head start is worth more than any cooking method.

The stalk is as good as the head. Peel it and slice it.

Frozen broccoli is blanched before freezing, so add a pinch of mustard powder to restore the missing enzyme.
