Lapsi (Nepali hog plum)

A fruit with a name of its own

In Nepal, lapsi is the fruit of Choerospondias axillaris, a deciduous tree in the cashew family, Anacardiaceae. Kew accepts this name; older botanical literature may call the species Spondias axillaris, its earlier name, which can also blur the distinction between lapsi and other fruits called hog plum. In Nepali the name is लप्सी (lapsi). “Hog plum” is a useful English gloss, but the Latin name is the more reliable identifier when a recipe or market label needs to distinguish the fruit.

Lapsi is not a single standardised ingredient: trees differ, and so do the fruits. A batch with less flesh takes more fruit to yield the same amount of pulp, while a sharper batch may call for a different balance of salt, sugar or spice, so “ripe lapsi” gives a starting point rather than an identical flavour in every basket.

In the kitchen, lapsi may arrive as ripe fruit or prepared pulp. The difference shapes the preparation: ripe fruit softens in cooking before the flesh is separated from its hard stone; prepared pulp is a smoother starting point. Those words describe form and ripeness, not a specific cultivar or harvest locality.

Nepal’s forestry manual records the tree at roughly 950 to 1,900 metres and describes it as a tall tree, with notes on how it is propagated. That altitude range ties lapsi to hill farms, and Kew’s native-range record for the species includes Nepal. For a cook the practical meaning is simple: lapsi is a seasonal hill fruit, and its character in the kitchen comes from fruit that is picked, sorted and processed close to where it grows.

Orchards, markets and household kitchens

Lapsi belongs to both hill orchards and household cooking. A 2003 Nepal field study recorded farmers distinguishing fruit by size, maturity, taste and pulp content, while families, local traders and urban processors handled the harvest at different scales. Fruit could be sold or bartered in more remote places; roads connected growers to markets where cooked and dried lapsi foods were sold. The fruit therefore has a working history of selection, transport and exchange as well as a place at the table.

In Kavrepalanchowk, a 2007 field report describes families crushing and boiling fruit for pickle or chutney and entrepreneurs making titaura for sale. A later Bhaktapur study lists sweet and hot candy, titaura, mada, pickle, jam and lapsi powder among the district’s products. These names point to different textures and occasions: a spoonable accompaniment beside a meal, a dried sweet-sour bite carried as a snack, or a pulp preparation kept for further cooking.

The 2003 field study places harvesting between September and January, depending on maturity and market demand. Fruit was generally picked before becoming fully ripe so that it would not rupture or rot in handling. Nepal’s forestry manual describes ripening from October to January. For the cook, those overlapping windows explain why early, firm market fruit and softer fruit may need different handling even within one season.

Lapsi also joins orchard and forest economies. A Nepal government fruit-development report describes the species as an agroforestry crop grown across many districts and notes its importance for hill farming communities; its survey treats distribution and current uses as practical questions for conservation and market development. Its geography does not mean every lapsi fruit comes from a cultivated orchard: local trees may be planted, managed or gathered under different arrangements. The tree’s value is not only the taste of its fruit but also the income and work attached to seasonal harvest and processing.

Taken together, the field studies describe a food that moves through several hands before it reaches a plate. Farmers judge fruit by size, maturity, taste and the amount of pulp; households crush and boil it for pickle or chutney; semi-commercial and commercial processors turn it into candy, titaura and mada for sale; and the Bhaktapur study adds jam and a powder to the list. Each stage asks something different of the fruit, which is why one tree can supply a family jar, a market snack and a packaged sweet in the same season.

Sourness, stone and flesh

A ripe lapsi is small and oval, with an edible layer around a notably hard stone. Forestry references describe a fruit roughly 2.5–3 centimetres long, though other regional botanical accounts give different measurements. Size is not a dependable quality grade by itself. For cooking, feel the flesh and taste a cut piece: a fruit that is still very hard and sharply astringent will behave differently from one whose pulp has softened and whose tartness has mellowed.

The hard central stone occupies space that a cook cannot turn into smooth pulp. Laboratory work on sampled fruit accessions also shows differences in measured sugars and organic acids among sampled fruits; those measurements do not give a fixed specification for a Nepalese market basket. The practical test remains to taste the fruit and see how readily its flesh softens and separates.

That bright, mouth-watering acidity is why lapsi suits the pickle jar, the candy pan and the souring spoon. It can cut through the richness of oil and roasted spices; sugar can turn its edge toward a sweet-sour balance; salt and chilli make it a sharper accompaniment. These are cooking relationships, not a claim that every recipe needs all three. Where a formula calls for pulp, the cook gets a smoother base; where it says whole or ripe fruit, peel and flesh may remain part of the texture and the stone has to be managed separately.

Lapsi flesh contains pectic material, and researchers have extracted pectin from it to measure the isolated material’s viscosity and gel properties. A pan of whole fruit is a different system: fruit maturity, available water, heat and added sugar all affect how its cooked pulp thickens. The laboratory result therefore cannot promise a jam-like set in a household pickle. Cook to the texture called for by the particular preparation, from loose relish to dense candy mixture.

From tree to kitchen

Tall lapsi trees make picking strenuous, and growers often harvest before the fruit is fully soft so it survives transport. At market, a basket may mix firm fruit with softer fruit.

At home, remove leaves and damaged fruit, then rinse the rest under clean running water. For a cooked pickle, the fruit can be boiled until its flesh softens; some family methods peel it and leave the pulp around the hard stone, while others work toward a separated pulp. The chosen form changes the finished food. Fruit left around its stone gives pieces to suck or nibble, whereas strained or scraped pulp makes a smooth base for candy, chutney or a thick condiment.

Suryabinayak municipal guidance describes keeping raw lapsi in a shaded room while it awaits processing. Soundness matters more than any fixed interval: sort out fruit that develops wet decay or visible mould. The same guidance gives separate pickle preparations. The cook chooses a method for its desired texture and serving time, rather than assuming all sweet-sour lapsi pickles keep alike.

The Suryabinayak municipal agriculture portal treats pickle and other lapsi products as separate preparations, each with its own method. A spiced, cooked pickle is a spoonable condiment; a sun-dried sweet is a chewy, portable one. The two start from the same pulp but end as different foods, which is why the cook should follow the method for the food wanted rather than treating one lapsi preparation as a template for another.

Drying yields several foods with different starting material. The 2003 study describes mada as a mat of crushed pulp and peel, sometimes seasoned with salt, sugar or spices and dried in the sun. Its account also records titaura among urban candy products; the 2007 field report identifies a commercial pulp cake by that name. In an ECS account of family practice, the tough peel removed after boiling is dried as paun, a fruit leather or cooking souring agent. That skin-based paun should not be confused with the pulp-based titaura or a jar of cooked achar.

The food around the food

At home, lapsi achar can enliven a plate of rice and lentils with a spoonful of tart, spiced fruit. A family account in ECS Nepal describes boiling the fruit and peeling it to make lapsi pickle. The same account describes pau kwa, a thick lapsi soup served during a Newar feast before the closing fruit and Juju Dhau. The soup’s place in that meal is distinct from the jarred pickle.

Behind a small jar is seasonal work: picking from high branches, sorting fruit, softening the flesh and dealing with peel and stone. Dried mats and candies add the work of crushing, spreading, seasoning and drying. Family batches are made at home; traders and small processors sell other forms through shops and markets. The same tree can thus feed a household table and an enterprise without those foods having the same recipe or texture.

Fresh fruit, cooked pulp and a finished dried sheet each offer a different kind of sourness. A piece of fruit gives its juice and flesh slowly around the stone. Smooth pulp disperses acidity through a sauce, while a dried strip concentrates it into a chew. Choosing among them is partly a question of the dish: a little pulp can sharpen a pan of vegetables, a spoonful of achar can sit beside a rich meal, and paun can be eaten or used as a souring ingredient.

Choosing, keeping and cooking

Choose sound fruit without wet decay or deep bruising. Softening flesh signals ripeness, but it does not tell you how sweet or sour the batch will taste, so taste a piece before measuring sugar or chilli.

For a pulp-based pickle, cook until the flesh can be worked away from the stone, then continue with the chosen recipe. Stir as water evaporates and the pulp thickens so it does not catch on the pan. Sugar rounds the tartness; salt and chilli heighten its savoury edge; toasted fenugreek or other spices give the fruit a warm, nutty counterpoint. Family formulas vary, and the choice between pieces and smooth pulp changes the eating experience as much as the seasoning does.

For a dried sweet, cooked pulp can be spread into a mat or cake; mada may also include crushed peel. A fruit-leather experiment compared particular pulp-and-sugar formulations and sensory preferences, showing that sweetness and drying form can be adjusted within a tested product. A homemade sheet needs its own drying method and endpoint; its chew, sourness and storage behaviour cannot be inferred merely from the name paun, mada or titaura.

Cooked pickle, dried candy and a fresh-fruit souring agent serve different purposes. A cooked achar can be prepared for a meal, while drying changes a soft pulp or peel into something portable and chewy. Fermentation is a different process again, and none of the lapsi foods described here is a fermented one. For keeping a batch, use the method’s actual storage directions; tart taste or a thick texture alone gives no reliable storage period.

Two pieces of laboratory work help explain why recipes for lapsi are written around taste rather than fixed numbers. A comparison of fruit from different provenances found different measured sugars and organic acids, so no single sweetness or sourness can be assumed for every batch. A fruit-leather experiment compared particular pulp-and-sugar formulations with a tasting panel, and its conclusions apply to the products it tested. Both point the cook to the same habit: taste the fruit, decide how much sugar, salt or spice it needs, and let the finished texture, a loose relish, a thick pickle or a chewy sheet, tell you when the cooking is done.

A place in the pantry

Lapsi’s appeal lies in how its pointed sourness changes with handling. Beside dal and rice it can be a spiced pickle; in a Newar feast it can become a warm soup; dried peel can become paun for chewing or souring a dish. Crushed pulp and peel make mada, while a sweetened pulp cake becomes a different market snack. Skin, flesh and stone each steer the cook toward a different food.
