Pak choi can be blanched and frozen to add to soups and stews. Snow peas originated in the Mediterranean, and were grown widely in England and Europe in the 19th century. They were called English sugar peas in France. The Chinese adopted these peas from the English, and call them Chinese snow peas. They have light green pods and sweetly scented flowers.
Snow peas grow best in a soil rich in phosphorus and potassium, and with plenty of organic matter.
Make successive sowings every 10 days in February and April. Snow peas are ready to harvest 50 to 60 days from sowing. Harvest regularly to keep plants producing. The sweet, tender pods can be eaten raw, lightly steamed or sauteed.
