How to choose and store curry leaves (kariveppila)

Curry leaves in a Kerala kitchen: the short answer

Good curry leaves, kariveppila (കറിവേപ്പില), are deep glossy green, firm, and smell strongly when you crush one between your fingers. To keep them, wash them, dry them completely, wrap them loosely in a paper towel or a thin cotton cloth, and store them in a closed box in the fridge. Moisture is the main enemy: wet leaves turn black within days. For anything longer than a week or two, freeze them or dry them in the shade.

Curry leaves go into the tempering of almost every Kerala curry, thoran and chutney, so most households need a small, steady supply rather than a big bundle that wilts. This guide covers the names, how to pick a good bunch, how to wash it, and four ways to make it last. You will also find curry leaves on our spice names list, alongside mustard seed, turmeric and the other everyday tempering spices.

The names you will hear

Two common mix-ups are worth clearing up. Curry leaves have nothing to do with curry powder, which is a blend of ground spices. They are also different from the European "curry plant" (Helichrysum italicum), a silvery garden herb that only smells a little like curry. The botanical name of the real curry tree is Bergera koenigii, still widely listed under its older name Murraya koenigii. It belongs to the citrus family and is native to the Indian subcontinent and parts of Southeast Asia.

Where the leaves come from, and why there is no season

The curry tree is evergreen, so kariveppila is available in every month. That is why you will not see it on our Kerala season calendar. Plenty of Kerala homes keep a tree in the yard or a plant in a pot and simply pick a sprig when they need one.

Commercial supply is a different story. A study of curry leaf genotypes by Tamil Nadu Agricultural University notes that the crop is grown mainly in Tamil Nadu's Coimbatore, Theni and Salem districts, with Coimbatore the largest, and that varieties such as DWD-1, DWD-2 and the local Tamil Nadu type Senkaampu are cultivated commercially. Many of the bundles that reach Kerala towns travel some distance from farms like these, which is one reason loose leaves can already be a few days old when you get them.

Choosing fresh curry leaves

• Colour. Look for deep, even green with a slight shine. Pale, yellowing or bronze leaves are old or stressed.
• Smell. Crush one leaf. Fresh kariveppila gives a sharp, almost citrusy aroma straight away. A faint smell means a faint flavour.
• Feel. Leaves should be firm and springy, and a fresh stalk snaps rather than bends. Limp, papery leaves have lost water and will not recover for long.
• Spots and slime. Skip bunches with black patches, wet or slimy leaves, or a musty smell.
• Underside check. Turn a few leaves over. Tiny insects, sticky residue or a sooty film mean the bunch came from an infested plant and will not keep well.
• Stalk or loose. Leaves still on their stalks generally hold up better than loose picked leaves, because they have been handled less and lose water more slowly.

Wash them well

Curry leaves are eaten without peeling, so washing matters. A study from the Pesticide Toxicology Laboratory at Tamil Nadu Agricultural University compared common household washes on curry leaves treated with known amounts of pesticide. A dilute (2%) lemon juice solution removed the most residue, about 36 to 57 percent depending on the chemical. A 2% tamarind solution came next at about 23 to 43 percent, followed by hot water and 2% salt water. Plain tap water removed the least, from about 4 to 28 percent.

First, a soak in a little lemon juice or tamarind water, followed by a rinse, does more than a quick splash under the tap. Second, no washing method in the study removed everything, so a thorough wash reduces residue but does not bring it to zero. Whatever you use, finish with clean water and then dry the leaves properly before storing them.

Storing curry leaves in the fridge

This works well as long as the leaves stay dry.

1. Sort. Remove any yellow, black or damaged leaves. One bad leaf in a closed box speeds up the rest.
2. Dry completely. After washing, spread the sprigs on a towel and let them air-dry until no water beads remain. This is the step people skip, and it is why leaves blacken.
3. Wrap loosely. Wrap the leaves, on the stalk or picked, in a dry paper towel or a thin cotton cloth. The wrap absorbs stray moisture.
4. Box it. Put the bundle in a closed box or a zip bag with most of the air pressed out, and keep it in the vegetable drawer, away from the coldest back wall.
5. Check twice a week. Change the paper if it feels damp and pick out any leaf that has darkened.

Kept this way, curry leaves usually stay green and usable for about a week or two. They lose aroma gradually, so use the oldest bundle first.

Without a fridge

For a few days, treat a bunch of stalks like cut flowers: stand them in a glass with a little water, keep the glass in a cool, shaded spot, and change the water daily. In a hot Gulf kitchen or a Kerala summer, move to the fridge, freezer or drying methods if you need them to last longer than that.

Freezing curry leaves

Freezing is the easiest way to keep a large bundle for months. Strip clean, completely dry leaves from the stalks, lay them flat in a zip bag or a shallow box, press out the air and freeze. Use them straight from frozen; there is no need to thaw. Frozen leaves turn darker and go limp once they warm up, but they keep much of their aroma for tempering.

Drying curry leaves

Drying suits leaves you plan to grind into powders or spice mixes. The National Center for Home Food Preservation gives general advice for drying leafy herbs that fits curry leaves well:

• Dry them indoors in warm, moving air, not in strong sun. Sun drying is not recommended because herbs lose flavour and colour.
• Spread the leaves in a single layer, not touching, on a cloth or paper, and turn them now and then.
• They are ready when they are crisp and crumble between your fingers.
• Store them in an airtight container in a cool, dry, dark place to protect colour and fragrance.

The TNAU residue study also notes that curry leaves are traded both fresh and dried because they keep their colour and flavour well after drying. Store dried leaves the same way as your other dried spices; our spice storage guide explains why light, heat and moisture are the things to avoid.

Quick comparison

If you live outside India

Fresh curry leaves can be harder to find abroad, and there is a plant-health reason for it. Because the curry tree is in the citrus family, its leaves can carry the Asian citrus psyllid, a pest of citrus trees. US agricultural researchers have studied quarantine treatments for infested curry leaves to inform rules on the trade in citrus foliage. In practice, check your destination's plant-import rules before packing fresh sprigs in your luggage, and lean on freezing and drying to stretch each bundle you get.

If you are planning a weekly list, our bilingual grocery list maker includes kariveppila along with the other tempering basics. For more on choosing Kerala ingredients, read our guides to picking spices in Kochi and choosing and storing coconut.
