The ripe seed of the black pepper vine with its outer skin removed. White pepper is hotter and earthier than black, with a faintly fermented note that Chinese, Thai and French cooks value.
What it is¶
White pepper comes from the same vine as black pepper, Piper nigrum. The difference is processing. For white pepper the berries are left on the vine until ripe or nearly so, then packed into sacks and soaked in water, traditionally in running streams or tanks, for roughly one to two weeks. The soft outer flesh rots (the process is called retting) and is rubbed or washed off, leaving the pale inner seed, which is then dried in the sun.
A second, cleaner method, decortication, mechanically grinds the skin off dried black peppercorns. It avoids the fermented note but produces a less characterful spice. Most white pepper sold is still water-retted.
Origins and history¶
White pepper has been known almost as long as black. Pliny the Elder, writing in the first century AD, listed white pepper at seven denarii a pound, above black at four and below long pepper at fifteen. It became a staple in China, where pale soups and stir-fries favour its colour, and in the classical French kitchen, where black specks in a béchamel or mayonnaise were regarded as a fault.
The island of Bangka, off Sumatra, became the great centre of production in the colonial era, and its port of Muntok gave its name to what is still considered the benchmark grade. Sarawak, in Malaysian Borneo, is the other well-known origin.
Flavour and aroma¶
With the skin goes much of the aromatic oil, so white pepper has less of black pepper's citrusy, piney fragrance. The piperine is in the seed, so the heat remains, and it can seem sharper and more direct for having less aroma around it.
Water-retted white pepper also carries a musty, faintly farmyard note, caused by compounds such as skatole and cresols that form during fermentation. In small quantities in a hot and sour soup it reads as savoury depth; in poorly processed pepper, or sniffed straight from the jar, it can be unpleasant. Good white pepper smells clean and hot, with only a hint of that funk.
In the kitchen¶
White pepper is the default pepper in much of China and South East Asia, and it is not there merely for appearance.
- Hot and sour soup: white pepper supplies the "hot"; 1 tsp ground per litre is typical, added near the end with the vinegar.
- Cantonese cooking: congee, wonton soup, salt-and-pepper squid and char siu marinades.
- Thai cooking: pounded with garlic and coriander root into the classic seasoning paste known as sam-gler, the base of many marinades and soups.
- Vietnamese pho and Singaporean bak kut teh, a pork rib broth built on white pepper and garlic.
- French and Scandinavian kitchens: béchamel, velouté, mashed potato, fish sauces, Swedish meatballs and Scandinavian fish dishes.
💡 Add late, and less
White pepper's heat is stronger and its off-notes grow with long cooking. Add it towards the end, and start with about three-quarters of the amount of black pepper a recipe calls for.
A common mistake is buying white pepper ready ground and keeping it for years. It goes flat and musty quickly; buy whole and grind in a dedicated mill, or buy small quantities.
Buying and storing¶
Whole white peppercorns keep for two to three years in an airtight container away from light, heat and humidity. Ground white pepper fades faster than ground black, and within six months or so can smell more of the barnyard than the spice. Look for cream to pale grey peppercorns that are smooth and round; darker, blotchy ones may be poorly processed. See storing spices.
Substitutes¶
- Black pepper: the natural swap, with more aroma and visible specks. Use a little more.
- A small pinch of cayenne pepper adds heat without colour in pale sauces, though not the flavour.
- Sichuan pepper is sometimes paired with white pepper in Chinese cooking but is not a substitute: it numbs rather than burns.
Pairs well with¶
Ginger, garlic, spring onion, coriander leaf and root, soy sauce, rice vinegar and sesame oil; also cream, butter, potato, fish, pork and eggs.
