Consumer tips
- 1
If foraging Purslane, be 100% certain of identification; toxic spurge grows in similar environments and looks deceptively similar.
- 2
Buy organic Bok Choy when possible, as leafy greens are often heavily sprayed with pesticides.
- 3
Add Purslane raw to dishes at the very last minute; heat destroys some of its delicate omega-3s and turns its texture slimy.
- 4
Bok Choy cooks incredibly fast—just 2-3 minutes in a hot pan keeps the stems crisp and the leaves tender.
