How to pick a good Bok Choy

How to pick

Color is your fastest cue: look for leaf blades that are a uniform deep, dark green — almost blue-green in the best heads. Then look at the stalks: fresh pak choi petioles are pure white (or pale jade on Shanghai baby types), thick, crisp, and rigid, meeting the leaves in a clean spoon-shaped base. Lift the head gently — fresh bok choy feels dense and heavy for its size, and the leaves hold their shape and stand upright rather than flopping over. At the cut stem base, a fresh head smells clean and mildly vegetal.

Red flags

• Brown spots, rusty streaks, or translucent water-soaked areas on the white stalks — decay starts in the petioles and spreads quickly
• A musty, sour, or ammonia-like smell at the stem base — the head is breaking down even if the leaves still look green
• A slippery or slimy film at the cut base or where outer leaves were trimmed — active rot
• A browned, dried, or split cut end at the bottom — the head was harvested or cut days ago
• Pooled water or condensation in bagged bok choy — standing moisture traps against the leaves and accelerates yellowing and rot

How to store

Refrigerate unwashed at 32–40 °F (0–4 °C) in a loosely sealed or perforated plastic bag with a slightly damp paper towel to keep humidity up without soaking the head. Use within 5–7 days. Wash just before use — standing moisture on the leaves speeds yellowing and decay.
