Keeping Salad and Herbs Fresh: How to Avoid Limp Leaves

Salad and fresh herbs are perishable, and they have a very short fuse. The leaves lose moisture in hours, not days, and the wrong spot in the fridge can turn a whole lettuce limp overnight. A few simple habits keep the leaves crisp for far longer.

Why the leaves go limp

A salad leaf is almost entirely water. When that water evaporates, the cells collapse, and you recognise the result as limp salad. Cold air draws the water out of the leaf more slowly, which is why the fridge beats the kitchen worktop.

The other cause is ethylene. Ripe fruit such as apples, pears, bananas, avocado and tomato gives off this gas, and leaves are especially sensitive: they yellow and brown at the edges much faster when they sit next to the fruit bowl. So keep the salad in a different drawer from the fruit, and see the guide to avocado, lemon and onion without plastic.

Too dry or too wet, the balance sits in between

Limp salad has two opposite causes. Too dry: the leaves lie out in the open and evaporate, and they turn thin and leathery at the edge. Too wet: the leaves were put away damp, or they sit in a completely sealed box where the moisture has nowhere to go. Then they turn slippery and brown, and the pile gives way from the middle.

The aim is damp air around the leaves, but no free droplets of water. That is why kitchen paper works: it soaks up the surplus and gives the moisture slowly back. And that is why a beeswax wrap beats cling film, because a little moisture escapes instead of turning into condensation.

How to keep your salad fresh, step by step

1. 1
   Only rinse the leaves if they need it

   If they are going to sit for a while, leave the rinsing until just before serving. If you do rinse now, use cold water.

2. 2
   Dry the leaves properly

   A salad spinner, or shake them in a clean tea towel. This step matters most.

3. 3
   Lay them loosely in a bowl

   Do not press the leaves together. They need air between them.

4. 4
   Put a sheet of kitchen paper on top

   The paper takes the surplus moisture. Change it when it feels wet.

5. 5
   Cover with a beeswax wrap

   Shape the sheet around the rim of the bowl with the warmth of your hand, so it holds as it cools.

6. 6
   Put the bowl in the salad drawer

   Look over the leaves after a couple of days and pick out any that have given up.

The drawer at the bottom of the fridge is built for exactly this: it is more closed off than the rest of the fridge, so the air holds more moisture. If your drawer has a slider with a humidity symbol, high humidity is for leaves and lower for fruit. Never push the leaves right to the back against the cold plate, because there they can freeze, and a frozen leaf goes limp straight away.

Herbs keep best in a glass of water

Herbs with stalks, such as parsley, coriander, dill and mint, are best treated like a bunch of flowers. Trim a couple of millimetres off the stalks, stand them in a glass with a little cold water, and change the water every other day.

Lay a beeswax wrap loosely over the top as a breathable hood. The herbs then hold on to their own moisture without sweating. Basil is the exception: it dislikes the cold and does best at room temperature, out of direct sun. Chopped herbs with no stalks go in a lightly damp tea towel.

Beeswax wraps as a breathable lid over the bowl

Beeswax wraps are cotton coated with beeswax and tree resin. The wax softens at 35 to 40 degrees Celsius, which is simply the warmth of a hand: you press the sheet around the rim of the bowl, and as it cools it holds the shape.

The difference from cling film is that the sheet breathes. A little moisture escapes, so you avoid the drops of condensation that otherwise drip down into the leaves, but enough stays behind that the salad does not dry out. The set holds three sizes, S, M and L, so the smallest covers half a cucumber and the largest a serving platter. There is more in the guide to using beeswax wraps and in the guide to covering bowls without cling film.

Wash the sheet in cold water with a mild soap, never hot, because the wax melts at around 62 to 65 degrees Celsius. The rest is in the care guide for beeswax wraps.
