Kale (Haak Jaisa), Bok Choy and Asparagus: A Desi Kitchen Guide

Here’s the honest verdict before anything else: kale, bok choy and asparagus are good vegetables, but palak, sarson and methi from your local stall give you similar nutrition for far less money. Still bought a bunch? Good. This guide shows how to pick and how to store kale, bok choy and asparagus so they don’t wilt in two days, and how to cook each one simply, with kale cooked saag-style, bok choy in a 3-minute stir fry and asparagus snapped at exactly the right point.

Kale: how to choose it, store it and cook it saag-style

Kale is a leafy cabbage that never forms a head. It’s the same plant species as band gobi, broccoli and ganth gobi, and a close cousin of Kashmiri haak, the collard green that Kashmiri homes cook with mustard oil and hing, which is why “haak jaisa” is a fair way to describe it. Pakistani and Indian farms now grow it for city supermarkets in the cool months. You’ll see three kinds: curly green kale, flat dark lacinato (sometimes called Tuscan or dinosaur kale) and purple-veined red kale.

How to choose kale

  1. Colour. Deep green or purple, never yellowing.
  2. Crispness. Leaves should feel firm and springy, and squeak slightly when you rub them. Limp, soft leaves are old.
  3. Size. Smaller leaves are more tender and less bitter; huge leaves with thick stems are better cooked.
  4. Stem ends. Moist and pale at the cut, not dry, split or brown.
  5. Smell. Fresh and green. A strong cabbage smell means it’s been sitting.

How to store kale

Wrap the unwashed bunch loosely in a dry paper towel or cloth, slip it into a bag and keep it in the vegetable drawer, where it lasts about 5 to 7 days. Washed kale keeps too, but only if it’s spun or patted properly dry, because wet leaves go slimy fast. For longer storage, strip the leaves off the stems, blanch them for 2 minutes, cool in ice water, squeeze into balls and freeze; they’ll keep for months and drop straight into saag or dal.

Kale saag (serves 4)

Strip 250 g kale from its stems by running your hand down the stalk, and chop the stems fine. Put the kale, stems, 250 g palak, 1 green chilli, a thumb of ginger and 1/2 cup water in a pot, cover and cook 15 minutes. Mash or blend coarsely with 1 tbsp makki atta and cook 5 more minutes, stirring. Temper with 1 tbsp ghee, 3 sliced garlic cloves and a pinch of red chilli. Kale on its own is chewier and more bitter than sarson, so mixing it with palak makes a softer, more familiar saag.

Want kale raw in a salad? Massage it. Tear the leaves, add a pinch of salt and a squeeze of lemon, and scrunch them with your hands for 2 minutes until they darken and soften. It changes the whole thing.

Bok choy: picking, cleaning and a quick stir fry

Bok choy (also written pak choi) is a Chinese cabbage with thick white or pale green stems and dark, spoon-shaped leaves. Surprisingly, it’s the same species as the shalgam (turnip) in your winter sabzi, just bred for leaves and stems instead of a root. Baby bok choy, the palm-sized kind, is the most tender.

  1. Stems. Firm, bright and crisp, snapping cleanly rather than bending.
  2. Leaves. Dark green and perky, with no yellow edges, holes or slimy patches.
  3. Base. Clean and pale. Brown, soft bases are starting to rot.
  4. Weight. Heavy for its size, meaning it’s still full of water.

Store it unwashed in a loose bag in the fridge and use within 3 to 5 days. Grit collects at the base, much like it does in leeks, so halve baby bok choy lengthwise, or separate the stems of a large one, and rinse under running water while you fan the layers apart.

Garlic bok choy stir fry (serves 2)

Heat 1 tbsp oil until very hot. Add 3 sliced garlic cloves, 1 tsp grated ginger and 1 sliced green chilli for 20 seconds. Add 300 g bok choy stems first and toss 1 minute, then the leaves for another minute. Splash in 1 tbsp soy sauce and 2 tbsp water, cover 30 seconds, and serve while the stems still crunch. Total: about 3 minutes.

Asparagus: the snap point, storage and asparagus vs shatavari

Asparagus spears are the young shoots of a plant that, left alone, grows into a tall fern. In Pakistan and India it’s mostly imported or grown in small amounts, so it’s expensive and often tired by the time it reaches the shelf. Pick carefully.

  1. Tips. Tight, closed and dry. Tips that have opened out, gone soft or smell musty are old.
  2. Stalks. Firm, straight and bright green (or white or purple, if that’s the variety), without wrinkles.
  3. Cut ends. Moist and fresh, not dried out, split or hollow.
  4. Even thickness. Choose a bunch of similar spears so they cook at the same speed. Thick spears aren’t necessarily tough.

How to store asparagus

Treat it like flowers. Trim 1 cm off the ends, stand the bunch upright in a glass with 2 to 3 cm of water, cover the tops loosely with a bag, and keep it in the fridge for 3 to 5 days, topping up the water. Asparagus loses sweetness quickly after picking, so sooner is always better.

Find the snap point

Hold one spear near the middle with one hand and near the base with the other, and bend gently. It snaps where the woody part ends. Line the rest of the bunch up against that spear and cut them all at the same length, which wastes less than snapping each one. Save the woody ends for soup.

Asparagus with zeera and garlic (serves 2)

Heat 2 tsp oil, crackle 1/2 tsp zeera, add 2 sliced garlic cloves and 250 g asparagus cut into 5 cm pieces. Stir fry 3 to 4 minutes on high heat until bright green and just tender, then finish with salt, black pepper, a pinch of chaat masala and a squeeze of lemon.

In the old books

People often search “asparagus vs shatavari” because the names get mixed up. Garden asparagus (Asparagus officinalis) and shatavari (Asparagus racemosus) are cousins in the same genus, but they’re different plants: we eat the young shoots of one, while Ayurveda uses the root of the other, describing it as a cooling, nourishing tonic, especially for women. That tradition belongs to shatavari root, not to the spears on your plate. Eating asparagus doesn’t give you shatavari, and shatavari as a medicine is a separate matter for a qualified practitioner.

Are they worth it? Palak, sarson and methi vs the new greens

This is the part most glossy health articles skip. Kale, bok choy and asparagus are healthy. So are the greens you already buy for a fraction of the price.

GreenWhere it shinesUsual cost here
KaleVitamins K, C and A; low oxalateHigh
Bok choyMild, crunchy, cooks in minutesMedium to high
AsparagusFolate, fibre, a special treatVery high
PalakFolate, vitamins K and ALow
SarsonVitamins K, C and A; winter classicLow in season
MethiFlavour, fibre, some ironLow

One real advantage of kale: it’s low in oxalate, so the calcium in it is absorbed fairly well, while palak’s calcium is largely locked up by its oxalate. Someone told to cut back on oxalate for kidney stones may find kale an easier green than spinach. Beyond that, palak, sarson and methi hold their own, and for most families they’re the better buy. Our guides to buying and storing palak, sarson ka saag and fresh methi leaves cover those properly.

Myth: kale is a miracle food

Kale got its halo from marketing more than from anything unique inside it. It’s a nutritious leafy green. So is almost every dark leafy green, and eating a variety of them, cooked in a little oil so your body takes up the fat-soluble vitamins, beats forcing down kale you don’t like.

Did you know?

  • Not everyone’s urine smells after asparagus, and not everyone can smell it when it does. Both come down partly to genes, and both are harmless.
  • One widely reported medical case involved a woman who ate over a kilo of raw bok choy daily for months and developed a serious thyroid problem. Normal cooked portions are nothing like that.
  • Kale, broccoli, cauliflower, cabbage and ganth gobi are all one species, Brassica oleracea, bred into very different shapes.
Worth knowing first

All three, and kale above all, are rich in vitamin K. If you take warfarin, you don’t need to avoid them, but keep the amount you eat steady from week to week and speak to your anticoagulation clinic before adding a daily kale smoothie or a big new habit; never adjust the medicine yourself. Very large raw amounts of kale or bok choy, such as daily green smoothies, aren’t a good idea for people with an underactive thyroid; cooked, normal portions are fine. Anyone on a kidney diet with a potassium cap should get portion advice from their renal team. Asparagus has a moderate purine content, though for gout, meat, seafood, sugary drinks and alcohol matter far more than vegetables, so ask your doctor rather than cutting it out. For children under 5, cook asparagus and kale stems until soft and cut them small, since raw pieces are a choking risk.

Kale, bok choy and asparagus: common questions

How do you store kale so it lasts longer?

Keep it unwashed, loosely wrapped in a dry paper towel inside a bag, in the vegetable drawer; it lasts about 5 to 7 days. For months, blanch it for 2 minutes, squeeze it dry and freeze it in portions.

What are kale benefits and side effects?

Kale gives you plenty of vitamins K, C and A, fibre and fairly well-absorbed calcium. The downsides are gas in some people, a big vitamin K load for anyone on warfarin, and thyroid concerns only with very large raw amounts.

Is kale good for diabetics?

Yes, it’s very low in carbohydrate and high in fibre, so it’s an easy vegetable to fill half the plate. Watch what comes with it, like fried kale chips or sweet smoothies with fruit.

Is raw kale good for you?

In salad-sized portions, yes, and massaging it with lemon and salt makes it much easier to chew and digest. Cooked kale is gentler on the stomach and fine to eat more often.

What is kale called in Hindi or Urdu?

There’s no standard name, so shops use “kale”. Its closest desi relative is Kashmiri haak (collard greens), which is why people sometimes describe kale as haak jaisa.

Is asparagus the same as shatavari?

No. They’re related plants in the same genus, but garden asparagus is eaten as young shoots, while shatavari is a different species whose root is used in Ayurveda. Eating asparagus spears isn’t the same as taking shatavari.

Why does my urine smell after eating asparagus?

Your body breaks down a natural sulphur compound in asparagus into smelly by-products that pass into urine within an hour or so. It’s harmless, and some people either don’t produce the smell or can’t detect it.

Is asparagus good for kidney patients?

Normal servings suit many kidney diets, as it’s only moderate in potassium. If you have kidney disease, gout or a potassium limit, check portions with your doctor or renal dietitian.

Can you eat bok choy raw?

Yes, young baby bok choy is crisp and mild enough to slice into a salad. Keep raw portions normal-sized and wash the base well.

Is kale good in pregnancy?

Yes, washed and cooked kale is a nutritious pregnancy green with folate and vitamin K. Wash raw leaves very thoroughly, and avoid unpasteurised juices or smoothies from outside stalls.

Is kale better than spinach?

Not overall; they’re different. Kale has more vitamin C and less oxalate, while palak has more folate and is cheaper here. Eating both, and other greens, is better than picking a winner.

What is kale season in India and Pakistan?

Kale grows best in the cool months, roughly October to March, when it’s freshest and cheapest. Summer kale is usually from the hills or has travelled far.
