Looking for vegetables that start with J? It is a trickier letter than C, P or S, but there are still some brilliant options worth knowing about. Some are everyday ingredients in supermarkets, while others are more common in Asian, Caribbean, Middle Eastern or Latin American shops.

This guide covers the most useful J vegetables, what they taste like, how to cook them, where you might find them in the UK, and how to save money when buying them. A few entries are technically fruits or stems in botanical terms, but they are used as vegetables in the kitchen, so they have earned their place here.

Vegetables That Start With J: Quick List

1. Jicama

Jicama is a crisp, pale root vegetable with a juicy texture somewhere between apple, pear and water chestnut. It is often eaten raw, which makes it handy if you want a crunchy vegetable for lunchboxes, salads or dipping platters.

In the UK, jicama is not always available in standard supermarkets, but you may find it in specialist grocers, Latin American shops, some Asian supermarkets or online produce boxes. It is sometimes labelled as Mexican turnip or yam bean.

How to use jicama

• Peel it and slice into sticks for dips.
• Grate into slaws with carrot, cabbage and lime.
• Dice into fresh salsa with tomato, coriander and chilli.
• Add thin slices to stir-fries near the end so it stays crunchy.
• Use instead of apple in savoury salads if you want less sweetness.

Money-saving tip

If jicama is expensive or hard to find, try mooli, white cabbage, kohlrabi or cucumber depending on the recipe. They will not taste identical, but they can give you a similar fresh crunch for less.

2. Jerusalem Artichoke

Jerusalem artichokes are knobbly root vegetables with a nutty, slightly sweet flavour. Despite the name, they are not from Jerusalem and they are not the same as globe artichokes. They are the tubers of a sunflower-like plant, which is why they are also called sunchokes.

They are usually in season in the colder months and can be found at farmers’ markets, veg box schemes, greengrocers and some larger supermarkets. Their uneven shape makes them a little fiddly to clean, but they are worth the effort.

How to cook Jerusalem artichokes

• Roast: Scrub well, cut into chunks, toss with oil, salt and pepper, then roast until golden.
• Soup: Simmer with onion, garlic, stock and a potato, then blend until smooth.
• Mash: Mix with potatoes for a nutty twist on ordinary mash.
• Gratin: Slice thinly and bake with cream, garlic and cheese.

Food note

Jerusalem artichokes are known for causing wind in some people, particularly if eaten in large portions. If you are new to them, start with a small serving and see how you get on.

3. Jalapeño

Jalapeños are one of the easiest J vegetables to find in the UK. They are technically a fruit, as all peppers are, but they are used as a vegetable in everyday cooking. Fresh jalapeños are usually green, medium-hot chillies with a bright, grassy flavour.

You will often find them fresh, jarred, pickled or sliced on pizzas and nachos. They are useful because they bring both heat and flavour without being as fierce as some smaller chillies.

Ways to use jalapeños

• Slice into tacos, wraps and burrito bowls.
• Chop into tomato salsa or guacamole.
• Add to chilli con carne, bean chilli or vegetable stew.
• Stuff with cream cheese, coat and bake for homemade jalapeño poppers.
• Pickle sliced jalapeños with vinegar, sugar and salt for a fridge-friendly topping.

Money-saving tip

Fresh chillies can go soft quickly. If you have more than you need, slice and freeze them on a tray before tipping into a freezer bag. You can cook them straight from frozen in sauces, curries and stir-fries.

4. Japanese Aubergine

Japanese aubergine, also called Japanese eggplant, is long, slim and often a deeper purple than the large aubergines commonly sold in UK supermarkets. It tends to have tender skin and a soft, creamy flesh when cooked.

You may spot Japanese aubergines in Asian supermarkets or specialist greengrocers. If you cannot find them, ordinary aubergines will still work in most recipes, though they may need a slightly longer cooking time.

How to cook Japanese aubergine

• Slice lengthways, brush with oil and grill until soft.
• Cut into chunks for Thai, Japanese or Chinese-style curries.
• Stir-fry with garlic, ginger and soy sauce.
• Glaze with miso, mirin and a little sugar, then roast or grill.

ReducedGrub tip

Aubergines are often reduced when they look slightly wrinkled, but they can still be perfectly usable. Avoid any with mould, leaking liquid or a very soft, collapsed texture. Slightly tired aubergine is ideal for curry, caponata or baba ganoush-style dips.

5. Japanese Radish

Japanese radish is more commonly sold in the UK as mooli or daikon. It is a long white radish with a crisp texture and a milder flavour than small red radishes. It can be eaten raw, pickled, simmered or stir-fried.

Mooli is usually good value in Asian supermarkets and international grocers. One large radish can stretch across several meals, which makes it a useful budget vegetable if you like fresh, crunchy sides.

Easy ideas for Japanese radish

• Grate and serve with soy sauce, sesame oil and spring onion.
• Cut into matchsticks for slaws and noodle salads.
• Quick-pickle with rice vinegar, sugar and salt.
• Add chunks to soups and broths, where it turns tender and mellow.
• Use in place of turnip in some stews.

6. Japanese Mustard Greens

Japanese mustard greens include leafy vegetables such as mizuna and komatsuna. Mizuna has feathery leaves and a peppery bite, while komatsuna has broader leaves and a mild mustard flavour. Both are quick-cooking and useful for bulking out meals.

Mizuna is sometimes found in mixed salad bags, especially those labelled as spicy or oriental salad leaves. Komatsuna is more likely to appear in Asian supermarkets or seed catalogues if you grow your own.

How to eat Japanese mustard greens

• Use young leaves raw in salads.
• Wilt into ramen, udon or miso soup.
• Stir-fry with garlic and sesame oil.
• Add to omelettes, fried rice or savoury pancakes.

Budget swap

If you cannot find mizuna or komatsuna, try spinach, rocket, pak choi, spring greens or kale. Choose based on texture: spinach for softness, rocket for pepperiness, and pak choi for juicy stems.

7. Japanese Pumpkin

Japanese pumpkin usually refers to kabocha squash. It has a dense, sweet flesh and a rich flavour that works well in both savoury and lightly sweet dishes. The skin is often edible once cooked, though it is best to scrub it well first.

Kabocha can be a little harder to find than butternut squash, but it appears in some Asian supermarkets and seasonal veg shops. If a recipe calls for kabocha and you cannot get it, butternut squash, crown prince squash or acorn squash can usually step in.

Best ways to cook kabocha

• Roast wedges with oil, salt and chilli flakes.
• Add cubes to Japanese curry or coconut curry.
• Steam and mash with butter or miso.
• Slice thinly for tempura-style fritters.
• Blend into soup with ginger and stock.

8. Jute Mallow

Jute mallow is a leafy green used in parts of Africa, the Middle East and Asia. It is also known as molokhia. You may occasionally see the older name Jew’s mallow, but molokhia or jute mallow are more commonly used in food contexts now.

The leaves have a distinctive texture when cooked, creating a slightly thickened, silky soup or stew. Frozen chopped molokhia is often easier to find than fresh leaves in Middle Eastern and African food shops.

How jute mallow is used

• Cooked into garlicky soups with stock.
• Served with rice, flatbreads or chicken.
• Added to stews for body and greenery.
• Used much like spinach, though the texture is different.

Money-saving tip

Frozen molokhia is often better value than fresh and saves time because it is already chopped. It is also handy for reducing waste, as you can use only what you need.

9. Jamaican Callaloo

Jamaican callaloo usually refers to amaranth greens, although the word callaloo can mean different leafy greens depending on the country and recipe. It has a spinach-like quality but with a bit more character and body.

In the UK, you might find fresh callaloo in Caribbean grocers, specialist markets or in tins. Tinned callaloo is convenient and useful for quick midweek meals, though fresh greens give the best texture if you can get them.

Ways to cook Jamaican callaloo

• Sauté with onion, garlic, thyme and a little chilli.
• Cook with saltfish for a traditional Caribbean-style dish.
• Stir into rice and peas.
• Add to soups and stews.
• Use instead of spinach in savoury fillings.

10. Young Jackfruit

Young jackfruit is another ingredient that is botanically a fruit but commonly used like a vegetable, especially in savoury cooking. Unlike ripe jackfruit, which is sweet and tropical, young green jackfruit has a mild flavour and a shredded texture when cooked.

It is often used as a plant-based alternative in pulled-style dishes, curries and tacos. In the UK, tins of young jackfruit in water or brine are widely available in supermarkets, health food shops and Asian grocers.

How to use young jackfruit

• Drain, rinse and simmer with barbecue sauce for loaded rolls.
• Add to coconut curries with potatoes and spinach.
• Cook with jerk seasoning for a Caribbean-style filling.
• Shred into tomato-based stews.
• Mix with beans to make a more filling taco or burrito filling.

Buying tip

For savoury recipes, choose young green jackfruit in water or brine, not ripe jackfruit in syrup. The syrup version is sweet and will not work well in curries or pulled jackfruit recipes.

Other J Vegetables and Vegetable-Like Ingredients

There are a few more J foods you may come across, though some are regional names, less common varieties or ingredients that sit on the edge of the vegetable category.

• Jersey Royal potatoes: Not a separate vegetable species, but a famous seasonal new potato grown in Jersey. Excellent boiled, steamed or served with butter and mint.
• Jingle bell peppers: A small sweet pepper variety. Like jalapeños, peppers are technically fruits but used as vegetables.
• Japanese turnip: A small, tender white turnip that can be eaten raw or lightly cooked. Sometimes sold as Tokyo turnip or salad turnip.
• Junsai: A Japanese aquatic vegetable, also known as water shield. It is not common in UK shops, but may appear in specialist Japanese cuisine.
• Jamboo or jambu leaves: In some regions, jambu refers to edible leaves or plants used in cooking, though names vary widely, so check carefully before buying or foraging.

Which J Vegetables Are Easiest to Find in the UK?

If you are shopping in a typical UK supermarket, the easiest vegetables beginning with J are usually:

• Jalapeños, fresh or jarred
• Young jackfruit, usually tinned
• Jerusalem artichokes, seasonally
• Jersey Royal potatoes, seasonally
• Mizuna, often in mixed salad bags

For jicama, mooli, Japanese aubergine, molokhia and callaloo, you will usually have better luck in international food shops, markets or specialist greengrocers. These shops can also be brilliant for value, especially on leafy greens, chillies and large root vegetables.

How to Save Money on Vegetables That Start With J

Some J vegetables are everyday budget buys, while others can be pricey because they are imported or less common. A few simple habits can keep costs down.

Shop in the right place

Asian, Caribbean, Middle Eastern and Latin American grocers often stock ingredients such as mooli, molokhia, callaloo, jackfruit and specialist aubergines at better prices than premium supermarket ranges.

Buy frozen or tinned when it makes sense

Frozen molokhia and tinned young jackfruit are convenient, long-lasting and often cheaper than fresh versions. They are also useful if you only need a small amount at a time.

Use substitutes confidently

If a recipe calls for a hard-to-find J vegetable, do not abandon the whole meal. Try these swaps:

• Jicama: Use kohlrabi, cucumber, mooli or cabbage.
• Japanese aubergine: Use ordinary aubergine.
• Japanese radish: Use mooli, turnip or red radish depending on the dish.
• Mizuna: Use rocket, spinach or pak choi.
• Kabocha: Use butternut squash or another firm pumpkin.
• Callaloo: Use spinach, spring greens or amaranth greens if available.

Plan around waste

Large vegetables such as mooli, kabocha and jicama can last across several meals if stored properly. Build a simple plan: raw salad one day, stir-fry the next, soup or curry after that. This is one of the easiest ways to make unusual vegetables better value.
