What is Napa Cabbage?

Napa cabbage (Brassica rapa subsp. pekinensis) belongs to the mustard family, alongside bok choy and regular cabbage. Its elongated, oblong head is made up of pale green, tightly packed leaves with tender white stalks.

Compared to regular cabbage (bắp cải), cải thảo has a milder, sweeter taste and softer leaves, making it perfect for quick cooking or raw salads.
