Everything You Need to Know About Green Peppercorns
Green peppercorns are young, unripe peppercorns picked fresh from the Piper nigrum vine, the same plant that gives us black and white pepper. They taste fresher and fruitier than black pepper, with a bright, peppery bite. You can buy them fresh on the stem, or preserved in brine or jars. In Thai cooking, where theyโre called prik thai on, theyโre a key ingredient in fiery dishes like jungle curry.

Peppercorns have a long history too. They were once so prized in Europe that they were accepted in place of money for rent and taxes, which is where the phrase โpeppercorn rentโ comes from.
What Are Peppercorns?
Peppercorns come from a plant known as Piper nigrum, a slow-growing perennial evergreen vine. It can take up to four years to start producing fruit and about seven years to reach its full potential, after which it can keep fruiting for up to 20 years. In the wild, Piper nigrum can climb as high as 10 metres, supported by its dark green oval leaves and small greenish-yellow flowers that bloom in summer.
Once the flowers blossom, they ripen into the peppercorns weโre familiar with. The fruit starts out green and stays that way until itโs harvested, or until itโs left to ripen further and turns red. Green, black and white peppercorns all come from the same plant. The main difference is how theyโre processed:
Green peppercorns are harvested while young and fresh. They can be used fresh, pickled or brined.
Black peppercorns are green peppercorns that have been left to dry. As they dry, they shrink and darken, developing the spicy, robust flavour most people associate with pepper.
White peppercorns come from fully ripened berries with the outer skin removed, leaving the pale inner seed. They have a milder, earthy flavour.
Are Green Peppercorns Good for You?
Like other peppercorns, green peppercorns contain piperine, the compound behind their peppery heat, which is being studied for its antioxidant properties. They also provide small amounts of minerals such as iron and vitamin K. Since you eat them in small quantities, think of them mainly as a way to add flavour without relying on extra salt.
How Green Peppercorns Are Used in Thai Cooking
In Thailand, fresh green peppercorns are often cooked whole, still on the stem, so they look beautiful in the bowl and release a burst of pepper as you bite into them. Theyโre a star ingredient in jungle curry (gaeng pa), a fiery, water-based curry made without coconut milk, where their freshness really shines. Try them in our Pork Thai Jungle Curry, made with Mae Jum Jungle Curry Paste.
If youโre new to them, eat just one or two per spoonful at first. Combined with a spicy curry, they pack a punch.
How to Use Green Peppercorns in Your Cooking
Add to sauces: crush brined or fresh green peppercorns and stir them into creamy sauces for steak, chicken or fish. Their gentle heat pairs perfectly with creamy, buttery bases.
Add to curries: add whole or crushed green peppercorns to your favourite Thai curry for an extra layer of flavour. They work especially well in green and jungle curries.
Enhance marinades: crush green peppercorns into marinades for grilled meats or seafood for a fresh, zesty flavour.
Use in dressings: stir a few crushed green peppercorns into a vinaigrette to give simple salads more depth.
Where to Buy and Store Green Peppercorns
Green peppercorns are less common than black or white pepper, but you can still find them in a few forms. Fresh green peppercorns are sold year-round in tropical regions but can be hard to find in the UK. If you live near an Asian supermarket or a speciality food shop, you may find them fresh. Some online retailers that specialise in Southeast Asian ingredients also sell them fresh when in season.
More commonly, youโll find green peppercorns preserved in brine or pickled, in jars from speciality shops or online. Once opened, keep brined peppercorns in the fridge, where theyโll last for several weeks.
When choosing fresh green peppercorns, look for tightly clustered berries with a slight sheen. Fresh green peppercorns are highly perishable, so use them quickly or preserve them.
Preparing and Cooking with Green Peppercorns
Green peppercorns are valued in French, Thai and Western European cooking. Their fresh, slightly fruity flavour makes them a versatile ingredient for seafood, poultry, grilled meats and creamy sauces.
Theyโre delicate, so if youโre using fresh ones, rinse them gently under cold water, as the berries fall off the stem easily. They need little preparation beyond a light rinse, and they add a pleasant pop to dishes when cooked.
French cooking makes great use of green peppercorns, particularly in peppercorn sauces. A creamy green peppercorn sauce pairs beautifully with steak, chicken or pork: the gentle heat and complex flavour cut through the richness of the cream for a well-balanced, indulgent sauce. Green peppercorns also go well with white wine, mustard and parsley, making them an excellent addition to seafood dishes, especially shellfish.
Frequently Asked Questions
Whatโs the difference between green and black peppercorns?
They come from the same plant. Green peppercorns are picked young and used fresh or brined, while black peppercorns are the same berries dried until they shrink and darken.
Are green peppercorns spicy?
Theyโre peppery rather than chilli-hot, and usually milder than dried black pepper. Fresh ones eaten whole can still give a sharp burst of heat.
Can I use brined green peppercorns instead of fresh?
Yes. Rinse them first to remove some of the salty brine, then use them in curries, sauces or marinades.
Green Peppercorns: A Unique Spice for Your Kitchen
Green peppercorns may not be as widely used as black or white pepper, but their unique flavour can lift a wide range of dishes. Whether youโre making a fiery Thai jungle curry, a creamy French sauce or a topping for grilled meats, green peppercorns bring a fresh, gently spiced complexity to your cooking. They can be harder to find in some places, but fresh or brined green peppercorns are well worth seeking out.

From Jumโs Kitchen
In Thailand, fresh green peppercorns arenโt a garnish. Theyโre part of everyday cooking, added whole to curries and stir-fries still clinging to the stem. In a bowl of gaeng pa theyโre impossible to miss, and each one bursts with a bright, peppery heat that lifts the whole dish without overwhelming it.
If youโve only met them brined in a jar, tucked beside the capers, you might not realise how differently they behave. Fresh green peppercorns bring a bright, almost citrusy heat that suits jungle curries and stir-fries. Brined ones are milder and slightly tangy, and work beautifully in creamy sauces. Once you know which to reach for, youโll start spotting them everywhere in Thai cooking, and cooking with them will feel completely natural.
