Frequently Asked Questions

How do you revive wilted romaine?

Trim the base and submerge leaves in ice water for 15–30 minutes. Crisp cell walls re-inflate as they absorb water. Dry completely before storing or dressing.

Should you wash romaine before refrigerating?

No — wash only immediately before use. Water left on leaves creates the perfect environment for bacterial growth and accelerates browning. Pre-washed store bags are an exception as they are treated and dried.

Is the darker outer romaine leaf more nutritious?

Yes — the dark green outer leaves contain significantly more vitamin K, folate, and beta-carotene than the pale inner heart. Save the hearts for texture and use outer leaves in cooked dishes.
