Selection
and storage
Fresh
broccolis are
available year around. In the store, choose fresh,
bright, compact, firm textured flower heads with rich
flavor. Avoid those with over matured featuring yellow flower buds,
excessive branches and hollow stem. Whenever
possible, go for organic farm products to get maximum health benefits.
Once at home,
rinse flower heads by dipping it upside down in salt
water for up to 30 minutes and then clean in running cold water before
use in order to remove any pesticide residues
and dust. Broccoli greens should also be treated in the same
way as you do in washing any other greens like spinach.
Whenever
possible, eat broccoli while they are fresh.
Otherwise, it can be placed in the
refrigerator wraped in a zip pouch where it may keep well for a few
days.

flower heads, stalks and leaves are edible. Broccoli
sections are being used in varieties of delicacies. Tough
stalks and thcik leaves are trimmed using paring knife.

boiling and
microwaving has been shown
