Long pepper

• pippaliपिप्पली

  Hindi

  The older pepper of South Asian and classical Mediterranean cooking, largely displaced by black pepper.

Hotter than black pepper and considerably sweeter and more complex, with a slow-building warmth that arrives after the initial sweetness and lingers. The pungency is recognisably piperine and the aromatic frame around it is entirely its own.

Warm and sweetly spicy, closer to a baking spice than to black pepper — cinnamon and cardamom are the usual comparisons — with a peppery sharpness behind it.

Dark grey-brown to near-black, a slender tapering cone with a visibly granular surface where the individual fruits are fused. Two to four centimetres long and hard as a nail.

Extremely hard and dense, resisting a knife and blunting a grinder. It is broken with a mortar or grated on a fine rasp rather than milled.

• Piperine — The pungency, typically at a higher concentration than in black pepper, which is why a smaller quantity goes further.
• Piperlongumine and related amides — Characteristic of this species and part of what distinguishes its warmth from black pepper’s.
• Sesquiterpenes — The sweet, warm, faintly cinnamon-like aromatic frame that makes long pepper read as a baking spice as much as a pepper.

Grate it, do not mill it. A long pepper spike is dense enough to damage a peppermill, so a fine rasp or a mortar is the tool, and grating it fresh over a finished dish is where it shows best — the sweet warm aroma is volatile and a pre-ground jar has lost it. Use less than you would use of black pepper, since it carries more piperine. For a braise or a stock, drop one or two spikes in whole and take them out before serving; long pepper holds its sweetness through long cooking where black pepper dulls. And treat its sweetness as an opportunity rather than an oddity: it works in syrups, on fruit and with chocolate in a way no other pepper does.

Pickles and regional Indian masalas, braises and stocks where a whole spike can be simmered and removed, dry rubs for meat, and — increasingly in restaurant cooking — as a finishing pepper grated over a dish. Its sweetness also suits fruit, syrups and chocolate, which is unusual for a pepper. It works with beef, lamb, game, root vegetables, tomato, chocolate, pear and red wine, and alongside black pepper, cinnamon, cardamom, cloves and ginger.

• grinding — Grated on a fine rasp or broken in a mortar rather than milled — the spike is dense enough to damage a peppermill. Ground fresh it is markedly better, as with any pepper.
• infusing — Whole spikes simmered in a braise, a stock or a syrup, giving warmth and sweetness gradually and removed before serving.
• toasting — Brief dry-toasting deepens the sweet aromatic note. It scorches less readily than a seed spice because it is so dense.
• boiling — Holds up to long cooking better than black pepper, whose aroma dulls; long pepper keeps its sweetness through a braise.

Grate a little and smell for sweetness rather than heat. Piperine is non-volatile and an old spike is exactly as pungent as a new one, so heat proves nothing — what fades is the warm cinnamon-like aroma that is the reason to buy long pepper rather than black.

• Heat with no sweet warmth behind it
• A soft or pliable spike, indicating damp storage
• Faint aroma when grated

• Volatilisation of the sweet sesquiterpene fraction, which is what distinguishes it from black pepper
• Slow oxidation towards a flat, merely peppery character
• Moisture uptake and softening if stored damp

Whole, and a small quantity. Long pepper keeps for years, is used a spike at a time, and is dense enough that a peppermill will not cope — a fine rasp or a mortar is what it wants. It is worth trying if you already like black pepper, because it is recognisably the same pungency wrapped in a sweetness black pepper does not have, and it is one of the few genuinely unfamiliar spices that needs no new technique. Indian and specialist grocers stock it; supermarkets generally do not.

• Long, straight, uniformly dark spikes rather than short broken ones.
• Hard and dense, with no give — a pliable spike has been stored damp.
• A sweet warm aroma when a little is grated, not merely a peppery one.
• Whole spikes rather than ground, which is barely sold and loses the sweetness that justifies the price.

Graded commercially on spike length, colour and piperine content. Retail buyers rarely have a choice, since the spice is uncommon enough that most shops stock one option.

Piperaceae

A climbing perennial vine of South and Southeast Asia, grown much as black pepper is, bearing slender fruiting spikes that are picked green and dried to near-black.

The Indian subcontinent and Southeast Asia, with P. longum concentrated in India and Nepal and P. retrofractum in Indonesia.

• India — major producer. Chiefly the Western Ghats and the north-east.
• Indonesia — major producer. Chiefly the Javanese species.
• Nepal — notable producer
• Sri Lanka — notable producer

Spikes picked while still green and unripe, which is when the piperine content is highest. A ripened spike is milder and less valued.

1. Picking green — Immature green spikes cut by hand.Why: Pungency peaks before ripening, so timing determines the grade.
2. Sun drying — Dried whole in the sun until hard and near-black, over several days.Why: The spike must dry through without softening, since it is dense.
3. Cleaning and grading — Graded by spike length, uniformity and colour. Longer, straighter, darker spikes command the higher price.

Graded on spike size, colour and piperine content. No consumer grade reaches retail, and the spice is uncommon enough that most buyers see only one option.

Little documented, largely because the morphology is unmistakable and the spice is rarely sold ground. The recorded risk is substitution between the Indian and Javanese species, which differ in size and pungency.

Grown as a perennial climbing vine on supports, and also gathered from semi-wild stands. Production is small and largely serves regional and traditional-medicine markets rather than the international spice trade.

Humid tropical, with shade and reliable rainfall — the same conditions black pepper needs, and it is often grown alongside it.

The pepper Europe knew first. Long pepper reached the classical Mediterranean before black pepper became dominant and was valued above it in Greek and Roman sources; it remained a significant European spice through the medieval period and then faded almost completely as black pepper became cheap and abundant. Its near-disappearance from Western cooking is one of the clearest cases in this dataset of a spice losing a market it once led.

A major commodity of the ancient and medieval spice trade that is now a minor one, traded largely within South Asia and to specialist markets. Much of the current crop serves Ayurvedic rather than culinary demand.

One of the more prominent spices in Ayurvedic tradition, where pippali is a component of trikatu and appears widely. Recorded as documented tradition. SpiceHQ holds no clinical source for long pepper and makes no health claim about it.
