Lettuce is a staple for summer salads, but its tendency to wilt and turn brown within days can be frustrating. The leafy greens spoil quickly due to their high water content and lack of protective skin, making them prone to dehydration and bacterial contamination.
However, produce expert Dan Holt from Hitchcock Farms has shared a foolproof method using a common kitchen staple: aluminium foil. 'If you've ever wondered whether wrapping lettuce in foil keeps it fresh, you have to try this trick,' Holt said. 'It can keep romaine lettuce crisp for as long as 30 days.'
The expert recommends washing the lettuce thoroughly under cold water, then drying it completely using a salad spinner or a clean tea towel. Next, lay out a sheet of aluminium foil, place a few paper towels on top, and wrap the lettuce loosely in the foil. The paper towels absorb excess moisture, maintaining ideal humidity levels.
The foil allows enough airflow to prevent condensation while trapping moisture, acting as a barrier against mould spores, bacteria, and ethylene gas. This gas, naturally released by some fruits and vegetables, accelerates spoilage in enclosed spaces. Stored in the crisper drawer of the fridge, the lettuce should stay fresh for at least a month.
If the lettuce does start to wilt, Holt offers an easy rescue: submerge it in ice-cold water for five minutes, then pat dry. 'This is often enough to shock the leaves back into shape so that you can use the lettuce for a few more dishes,' he added.
