How to choose and store ginger (inji) and dry ginger (chukku)

Inji in a Kerala kitchen: the short answer

Good fresh ginger, inji (ഇഞ്ചി), feels hard and heavy for its size, has smooth, tight skin and smells sharp and clean where a knob is snapped off. Skip pieces that are wrinkled, soft, damp or spotted with mould. At home, keep it whole, unpeeled and dry: a loosely closed bag in the fridge keeps it in good shape for weeks, and the freezer keeps it for months. Dried ginger, chukku (ചുക്ക്), is a different product and needs a dry, airtight, cool spot instead.

Ginger goes into something almost every day in a Kerala home, from inji curry and pickles to sambharam, the spiced buttermilk drink. Both inji and chukku are on our spice names list.

The names you will hear

The botanical name is Zingiber officinale, and the plant belongs to the same family as turmeric and cardamom. Wikipedia traces the English word back through Latin, Greek and Sanskrit to an ancient Dravidian word, the root that also gave Malayalam inchi-ver, "ginger root". India is the largest grower, with about 45 per cent of world production in 2023.

When Kerala ginger is harvested

When ginger is dug depends on what it is grown for. FAO's post-harvest compendium gives about 5 months after planting for ginger sold fresh, 5 to 7 months for preserved ginger, and 8 to 9 months, when the leaves start turning yellow, for ginger that will be dried. The Malayalam Wikipedia article on inji gives the Kerala pattern: green ginger is lifted around the sixth month, while seed ginger and ginger for chukku are best around the eighth, with seed ginger dug in December and January and kept through the hottest months, April and May, until planting. Because mature roots keep well, fresh ginger is easy to find in most months.

Young ginger or mature ginger?

FAO notes that ginger for fresh use and preserves is harvested while still tender, low in pungency and fibre, before it is fully mature, while full maturity brings more oil, more pungency and more fibre. In the market that shows up as two quite different roots:

• Young ginger has thin, almost translucent skin, juicy pale flesh and a mild taste, which is why it is the favourite for pickling. Buy it in small amounts and use it first.
• Mature ginger has tougher, papery tan skin, firmer and more fibrous flesh and a sharper bite. This is the everyday ginger of Kerala curries and chutneys, and it keeps far better.

Choosing ginger at the stall

• Press it. Good ginger is rock hard. Any give, soft patches or a spongy feel means it is losing water or starting to rot.
• Look at the skin. Choose smooth, taut skin with a slight sheen. Deep wrinkles mean the root has already dried out and turned more fibrous.
• Check the cut ends and joints. Ends should be dry and pale yellow, not dark, wet or fuzzy. Look carefully between the fingers of the root, where soil and mould hide.
• Snap a small knob if the seller allows it. Fresh ginger breaks cleanly, shows juicy pale yellow flesh and releases a strong, clean smell. Long, hair-like fibres sticking out of the break mean the root is old and stringy.
• Prefer large, branched pieces. Every broken surface dries and can grow mould, so one big hand of ginger keeps longer than a pile of small broken bits.

If you are sending someone else to the market, add inji and chukku to our bilingual grocery list maker so both names are on the list.

How to store fresh ginger

What the trade does

FAO's compendium says fresh ginger keeps best cold and humid, around 10 to 12 °C with high humidity. In one study it cites, Hawaiian ginger stayed stable for 28 weeks at 12.5 °C and 90 per cent relative humidity, while at 22 °C and 70 per cent humidity it lasted 20 weeks before water loss and fibre made it unsaleable. The Indian Institute of Spices Research, based in Kozhikode, recommends polyethylene bags with about 2 per cent ventilation, which stop ginger drying out without trapping enough moisture to grow mould. At home the same two goals apply: slow the drying, and avoid wet surfaces.

On the counter: for a week or two

Whole, unwashed, unpeeled ginger is one of the sturdier fresh ingredients, but a hot, humid Kerala or Gulf kitchen is much harder on it than the 22 °C of that study. Keep a small amount in a basket or open bowl in a shaded, airy spot away from the stove, and plan to use it within a week or two. Do not keep it in a closed container at room temperature, where condensation encourages mould.

In the fridge: whole, dry and loosely bagged

1. Brush off soil but do not wash the ginger before storing it; dry it with a cloth if it is damp.
2. Leave the skin on. Peeled or cut ginger dries out and discolours much faster.
3. Wrap it in a dry paper towel and put it in a bag or box that is closed but not airtight, or a bag with a few small holes, the home version of the ventilated bags the institute recommends.
4. Keep it in the vegetable drawer and check it every week. Change the paper if it gets damp, and trim any dried-out ends before use.

Stored like this, whole ginger usually stays usable for several weeks. A home fridge runs colder than the 10 to 12 °C the trade uses, so expect weeks rather than months.

In the freezer: for months

For anything longer, freeze it. Freezing is the simplest way to keep a large batch, for example after a home-garden harvest. Freeze it whole and unpeeled, or peel it and cut it into thumb-sized pieces first, then pack it in a freezer bag with the air pressed out and label it with the date. Frozen ginger stays hard enough to grate without thawing; once thawed it turns soft and watery, so take out only what you need and use it straight from the freezer.

Storing dry ginger (chukku)

Chukku is ginger dried after harvest, usually peeled or scraped and then sun-dried for about a week; FAO notes it should be dried to 8 to 10 per cent moisture. It is far more stable than fresh ginger, but it does lose flavour. FAO reports that dry ginger kept at room temperature (23 to 26 °C) lost up to 20 per cent of its oleoresin, the fraction that carries its pungent flavour, within 3 months, and recommends cool storage at 10 to 15 °C. At home that means:

• Keep whole chukku in an airtight glass or steel jar, away from the stove, sunlight and steam.
• Buy it in small amounts and break or grind it only as you need it.
• In a very hot, humid season, the fridge is a sensible place for a well-sealed jar; let the jar reach room temperature before opening it so moisture does not condense inside.
• Check for tiny holes or powdery dust, signs of storage beetles; FAO names the cigarette beetle as a pest of dried ginger.

Our spice storage guide applies the same rules to the rest of the spice shelf, and the Kochi spice-buying guide explains how to judge dry ginger by look and smell.

When to throw ginger out

• Soft, mushy or wet patches, especially at cut ends.
• Fuzzy white, grey or green mould on the skin or between the fingers.
• Flesh that is grey or dark instead of pale yellow.
• A sour or musty smell instead of a sharp, clean one.

Ginger that is only wrinkled and dry is old rather than spoiled: it will be more fibrous, but if the inside is firm and smells right it is still fine to use. Green shoots mean the root has started to grow; use it soon, or plant it.
