How to store and identify fresh ruby leaf lettuce
Ruby leaf lettuce stays fresh in the refrigerator for 7–10 days.
Ruby leaf lettuce is prized by home cooks and chefs alike for its striking deep red and green hues, along with a mild, nutty flavor. Because of its unique structure, it can be more susceptible to wilting or becoming slimy if not handled correctly compared to standard iceberg varieties. To maintain that signature crunch and vibrant color, proper humidity control in the refrigerator is essential. When you notice signs like yellowing leaves, moisture buildup at the base, or a slippery texture, it is time to evaluate its quality. This guide explores the timeline of freshness for ruby leaf lettuce, helping you decide exactly when to keep it on the salad plate and when to toss it out.
