To Buy:
Look for fresh young peas with a bright green, waxy pod. Avoid yellow, split or dry-looking pods.
Garden peas can also be bought frozen or in cans. Peas freeze very well, holding their nutritional goodness. Avoid canned peas, they are horrible.
To Store:
Buy them the day you plan to eat them or the day before. Store them in a plastic bag in the crisper section of the refrigerator.
Tips & Tricks:
500g pea pods will yield approx 1 cup shelled peas.
