Shaljam (Turnip): How to Pick Tender Ones and Cook Them Well

Most people who say they hate shaljam were served a big, old one. Here’s how to choose turnip that’s sweet: pick small, heavy, smooth ones with fresh leaves, about the size of a tennis ball or smaller. This guide covers picking, whether turnips should go in the fridge, what they honestly offer, the leaves, shaljam gosht and achar, and the thyroid worry.

Why some shaljam is bitter and woody

A turnip keeps growing if nobody pulls it. As it swells, the inside turns stringy and the sharp, mustardy taste gets stronger. That bite comes from natural sulphur compounds (glucosinolates), the same family that gives sarson and mooli their kick.

Old turnips stored warm lose water and sweetness too, so a woody, bitter shaljam is almost always one of three things: too big, too old, or stored badly, and all three are fixable at the stall.

How to choose turnip: the stall checklist

1. Size first. Pick turnips 5 to 8 cm across. Baby turnips smaller than a golf ball are the sweetest of all and barely need peeling.
2. Lift it. A good one feels heavy for its size. Light means it has dried out and gone spongy inside.
3. Press with your thumb. It should be rock firm. Any give or wrinkling means old stock.
4. Look at the skin. Smooth and shiny, with a clean purple blush at the top. Skip deep cracks, brown soft patches, worm holes and lots of hairy side roots.
5. Check the leaves. Bright, perky green leaves mean it came out of the ground recently. Yellow or slimy leaves mean it’s been lying around, even if the root looks fine.
6. Look at the base. One thin taproot is normal. A thick, woody base usually means a woody inside.

If the seller will cut one open for you, the flesh should be white, crisp, wet-looking and even all the way through, and grey rings, hollow spots or a dry cottony centre are the signs that this batch was pulled too late or has been sitting in a warm godown for too long. Move on.

Should you keep turnip in the fridge?

Yes. In a warm kitchen, turnips soften and get more bitter within days.

• Cut the leaves off first, leaving about 2 cm of stem. Leaves keep drawing water out of the root.
• Roots: unwashed, in a bag or box in the vegetable drawer, for 1 to 2 weeks.
• Leaves: wrap loosely in a dry cloth or paper, put in a bag, and use within 2 to 3 days. They wilt fast.
• No fridge? In a cool room in December, a basket in the dark will do for 4 to 5 days. Never a closed plastic bag at room temperature. They sweat, then rot.
• Freezing: peel, cube, blanch 2 minutes in boiling water, cool, dry and freeze. They go softer after freezing, so use them in gosht or soup, not salad.

How to prepare shaljam so it isn’t bitter

Wash under running water, scrub the top where soil collects, and skip soap or bleach.

Small young turnips only need their top and tail cut off; bigger ones have a tougher, more bitter layer just under the skin, so peel them thickly, about 2 to 3 mm, and that one step removes a lot of the sharpness.

For a milder taste, boil the cubes in plenty of water for 3 to 4 minutes, drain, and then cook them in your masala, because pouring off that first water takes a good part of the bitterness with it and leaves you with a turnip that even fussy eaters at the table won’t notice.

A little gur, onion or tomato balances the bite. Hence all that gur in desi turnip recipes.

Are turnips good for you?

Yes, in a quiet, steady way. A cup of cubed turnip has about 35 calories, a couple of grams of fibre and around a quarter to a third of a day’s vitamin C. It’s mostly water, so it fills you up for very little.

What it’s good for:

• Bulk without many calories. Adding turnip to a gosht stretches the dish, so each plate carries less meat and fat while the pot still feeds the whole family, which is exactly how thrifty winter kitchens have always used it.
• Fibre for regular bowels.
• Winter vitamin C when summer fruit has gone.

What’s hype: shaljam doesn’t clear your chest, “purify” blood or fix joint pain; these are traditional ideas. The leaves, though, are more nutritious than the root; more on that below.

Turnip greens: don’t throw them away

Shaljam ke patte are edible and quite nutritious. They’re rich in vitamin K, folate, vitamin C and calcium, and taste like a slightly peppery sarson.

• Cook them with sarson and palak for a mixed winter saag.
• Fry them with garlic and chopped turnip for a quick sabzi.
• Only use fresh, green leaves. Chop off thick stalks. Wash in several changes of water, as grit hides in the folds.

If you take warfarin, turnip greens (like all dark leafy greens) are high in vitamin K, the vitamin that helps blood clot, so you don’t have to avoid them, but you should keep the amount you eat roughly steady from week to week and tell your doctor before you change your diet in a big way, such as starting a daily saag habit in winter. Consistency matters most.

Recipes: shaljam gosht, achar and a quick bhujia

Shaljam gosht (serves 4)

1. Brown 2 sliced onions in 4 tablespoons oil. Add 500 g mutton or beef, 1 tablespoon ginger-garlic paste, 1 teaspoon salt, half a teaspoon turmeric and 1 teaspoon red chilli powder.
2. Add 2 chopped tomatoes and cook until the oil separates.
3. Add water and pressure-cook the meat until nearly tender (mutton about 20 to 25 minutes).
4. Peel and cube 500 g small turnips, add them with a teaspoon of gur, and simmer 15 to 20 minutes until soft enough to mash lightly with a spoon.
5. Finish with garam masala and chopped coriander. Eat with roti.

Gobi-gajar-shaljam achar (Punjabi winter pickle, small batch)

Cut 250 g each of turnip, cauliflower and carrot into bite pieces. Blanch 1 minute, drain and dry in the sun or on a cloth for a few hours until no water is left. Heat 150 ml mustard oil until it smokes, cool slightly, add 1 tablespoon ginger-garlic paste, then 2 tablespoons crushed rai, 1 tablespoon salt and 2 teaspoons red chilli. Mix with the vegetables. Separately melt 100 g gur in 100 ml vinegar and pour over. Keep in a clean glass jar, stir daily with a dry spoon, and it’s ready in 4 to 5 days. Refrigerate after opening; throw it out if it smells off or grows fuzz.

Shaljam bhujia

Fry half a teaspoon zeera in 1 tablespoon oil; add 1 chopped onion, 2 green chillies, 3 peeled and chopped turnips, salt and a pinch of turmeric, then cover and cook 12 to 15 minutes on low; mash lightly, then add a squeeze of lemon and fresh coriander.

Good combos: turnip with meat, lentils or chana, which give body to its light, watery flesh, and turnip with gur or tomato to soften the bitterness. Fear none of them.

Myth: shaljam ruins your thyroid

The truth: turnips belong to the cabbage family, and very large amounts of raw cabbage-family vegetables can slightly affect how the thyroid uses iodine. In real diets, cooked turnip in normal portions isn’t a problem for most people, including those on thyroid medicine. Cooking reduces these compounds further, and using iodised salt covers the iodine side. Our longer piece on gobi, band gobi and thyroid foods goes into the detail.

Why people believe it: the word “goitrogen” sounds scary and gets passed around on WhatsApp without the part about amounts, which is the whole point, because the worry applies to very large daily helpings of raw cabbage-family vegetables in people who are short of iodine, not to a plate of shaljam gosht on a Sunday. If you have a thyroid condition, ask your doctor about your own diet.

Myth: turnip is a “cold” food that gives you flu

Colds and flu come from viruses, not vegetables; in Unani thinking foods are sorted as hot or cold by nature, and elders differ on where shaljam sits. That’s tradition, not a cause of illness.

Surprising turnip facts

• Before pumpkins, people in Ireland and Scotland carved lanterns out of turnips for Halloween.
• The turnip is the same species as Chinese cabbage and bok choy, just bred for its root instead of its leaves.
• That purple top is the part that grew above ground in the sun; the white part stayed in the soil.
