How do you wash leafy greens and keep them fresh?
A step-by-step way to wash and dry parsley, arugula and lettuce so they stay crisp in the fridge for 7 to 10 days.
Short answer
Add 1 tablespoon of vinegar to 5 liters of cold water, soak the greens 5 minutes, then rinse them 30 seconds in a colander. Dry them completely in a salad spinner or on a cotton towel. Roll the dry leaves loosely between 2 paper towels, put the roll in a lidded container and store it in the crisper drawer at 4 °C. Swap the paper towel every 2 days.
What you need
Step by step
Sort and untie the bunch
Take off the rubber band or tie, then pull out and discard every yellow or bruised leaf. Trim 1-2 cm off the root end, where the soil packs in tightest. A single spoiled leaf gives off enough moisture and ethylene to rot the whole bunch in 2 days.
Soak in vinegar water
Fill the bowl with 5 liters of cold water and stir in 1 tablespoon of vinegar or 1 teaspoon of baking soda. Push the greens all the way under, leave them 5 minutes, then swish them gently by hand. Soil and grit sink to the bottom while the vinegar cuts the bacteria load on the surface.
Rinse under running water
Lift the greens up out of the water rather than pouring the bowl over them, or the grit at the bottom lands right back on the leaves. Rinse them in a colander under cold running water for 20-30 seconds. This rinse keeps any vinegar or baking soda taste off the leaves.
Dry them completely
Fill the salad spinner no more than halfway and spin 20-30 seconds, working in two batches so nothing crowds. With no spinner, spread the leaves in a single layer on a cotton towel, cover them with a second towel and wait 10 minutes. One drop of water left on a leaf is enough to start the rot.
Wrap in paper towel
Lay the dry greens between 2 paper towels and roll them up loosely, without pressing. Put the roll into a lidded storage container or a perforated bag. Fill the container no more than two thirds so air can still move around the leaves.
Store at 4 °C in the crisper
Put the container in the crisper drawer at the bottom of the fridge and set the fridge to 4 °C. Keep apples, bananas, tomatoes and melon out of that drawer; the ethylene gas they release turns the leaves yellow in 2-3 days.
Change the towel every 2 days
Open the container and touch the paper towel; if it feels damp, swap in a fresh one and pick out any yellowing leaves. With that check, parsley and arugula stay crisp for 7-10 days and a head of lettuce for 10-12 days.
Tips
Watch out
The most common mistake is bagging greens while they are still wet: slimy rot starts at the leaf bases within 24 hours and the whole bunch is lost. Do not use bleach, dish soap or chlorine tablets either; they are not food safe, and vinegar or baking soda does the job.
Frequently asked questions
+Does baking soda work instead of vinegar?
Yes, 1 teaspoon of baking soda per 5 liters of water does the same job. Rinse for 30 seconds under running water afterward so no residue is left behind.
+How long can washed greens sit on the counter?
Do not leave dried greens at room temperature for more than 2 hours. In summer that drops to 1 hour, since the leaves wilt and lose water fast.
+I have no salad spinner. Can I use a hair dryer?
No, the warm air wilts the leaves instantly. Put the greens in a clean pillowcase and swing it for 10 seconds outside; that does the spinner's work.
+Can I freeze leafy greens?
Chopped parsley, dill and mint keep up to 6 months in a freezer bag, but they go limp once thawed. Use them in soups and cooked dishes only, not in salads.
