White sapote: what it is, taste, benefits and how to eat it

What is it?

The white sapote is one of the most singular and traditionally prized fruits of Mexican cuisine: a round or oval fruit of five to twelve centimetres in diameter, with a thin skin of yellow-green to light green when ripe, and inner whitish-yellow pulp, creamy, sweet and with a characteristic aroma reminiscent of banana and pear. It contains several large rounded seeds, brown or yellow, that are discarded. Its flavour is intensely sweet, syrupy, with notes that combine ripe banana, pear, peach and a floral touch. The texture is very soft, almost gelatinous when perfectly ripe, which has earned it a reputation as a noble but delicate fruit. It is traditionally eaten fresh, split and eaten with a spoon, as well as in aguas frescas, ice creams, ice lollies, jams, mousses and, in some regions, in artisanal alcoholic drinks. However, its main fame in Mexico comes from its medicinal properties: it has been traditionally used as a natural sedative and to treat hypertension, properties that have been confirmed by modern pharmacological research.

Origin and history

The white sapote is native to the central Mexican highlands, particularly the temperate regions of the Trans-Mexican Volcanic Belt, where its use is documented from pre-Hispanic times. The name comes from the Nahuatl iztactzapotl, where iztac means white and tzapotl, sapote or sweet fruit. Fray Bernardino de Sahagún in the Florentine Codex and Francisco Hernández in his Historia natural de la Nueva España, both from the sixteenth century, document the white sapote among the important fruits of Mexica cuisine, also recording its medicinal uses that were already known to the pre-Hispanic cultures. It belongs to the genus Casimiroa of the Rutaceae family, the same as citrus, which explains some aromatic notes reminiscent of that family. The main species is Casimiroa edulis, although there is also Casimiroa tetrameria with similar fruits but different properties. Its domestication is placed in central Mexico at least 2,000 years ago. After the conquest, the Spanish took the white sapote to parts of the Caribbean, California and other regions of similar climate. The main producing regions of Mexico are the State of Mexico, Michoacán, Querétaro, Hidalgo, Guanajuato and Jalisco. CONABIO documents Casimiroa edulis as a native species of great agroforestry and medicinal importance in traditional Mesoamerican systems.

Characteristic ingredients

The white sapote is Casimiroa edulis, an evergreen or semi-deciduous tree of the Rutaceae family that can reach fifteen metres in height, with palmate compound leaves and small white flowers. The fruit is harvested when it begins to soften to the touch and finishes ripening in one to five days at room temperature; it is ready when the skin yields to gentle pressure and begins to develop brown spots. To prepare, it is split and the pulp eaten with a spoon, removing the large seeds that are discarded. The pulp contains vitamin C, vitamin A, potassium, calcium, magnesium and dietary fibre. The seeds, leaves and bark contain pharmacologically active compounds, particularly casimiroin, casimirosa and several flavonic alkaloids that have sedative, hypotensive and anti-inflammatory effects documented by researchers such as José Luis Magaña Mota and published in pharmacological journals. In Mexican traditional medicine, the leaves and seeds (toasted and ground) have been used for centuries to treat insomnia, anxiety, hypertension and rheumatic pains; however, the seeds in large quantities are toxic and should be avoided. In cooking, in addition to fresh consumption, the white sapote is used in aguas frescas, artisanal ice creams, ice lollies, jams, mousses, shakes with milk and, in some regions, in artisanal liqueurs. In contemporary cuisine, Mexican chefs have incorporated it into modern desserts and dairy-free mousses for its naturally creamy texture.

Cultural significance

The white sapote is biocultural heritage of Mexico and an emblem of the fruits of the temperate Mexican highlands, as well as being one of the most recognised medicinal plants of traditional herbalism. Its sedative and hypotensive properties, known to the pre-Hispanic cultures and passed down across generations, have been confirmed by modern pharmacological research that has identified the active compounds responsible. Traditional Mexican cuisine, inscribed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity in 2010, includes native fruits such as the white sapote among its cultural components. Economically, the white sapote supports rural producers in the State of Mexico, Michoacán, Querétaro, Hidalgo, Guanajuato and Jalisco, grown mainly in backyard systems and small orchards. The White Sapote Fair in some towns of the State of Mexico keeps the regional tradition alive. SADER (gob.mx) has highlighted the potential of the white sapote both as a premium fruit and as an ingredient for the nutraceutical industry, given its profile of bioactive compounds. Mexican researchers at the UNAM, the IPN and CINVESTAV have documented the therapeutic potential of the compounds in the white sapote, opening possibilities for developing phytomedicines based on this ancient plant. Contemporary chefs such as Margarita Carrillo Arronte and Pablo Salas have incorporated it into modern menus.

Frequently asked questions

What is the difference between white sapote and black sapote?

Although they share the generic name sapote, they are botanically very different. The white sapote (Casimiroa edulis, Rutaceae family) is a relative of citrus, with creamy whitish-yellow pulp and a sweet banana-pear flavour. The black sapote (Diospyros nigra, Ebenaceae family) is a relative of persimmon and ebony, with very dark pulp and a chocolate-plum flavour. Their appearance and flavour are completely different despite the shared name.

What does white sapote taste like?

It has a sweet, syrupy and aromatic flavour, with notes that combine ripe banana, pear, peach and a characteristic floral touch. The texture is very soft, almost gelatinous when perfectly ripe, almost like a natural flan or pudding. The aroma is fragrant and distinctive, easy to identify. Some varieties have more citrus notes reminiscent of their citrus relatives.

How is white sapote served?

Fresh, it is split in half and the pulp eaten with a spoon, removing the large seeds. It is also prepared in aguas frescas (blended with water and a little sugar), artisanal ice creams, ice lollies, jams, mousses, shakes with milk and, in some regions, in artisanal liqueurs by maceration. In contemporary cuisine it is used in modern desserts and as a natural base for dairy-free mousses. The seeds are not eaten because they are toxic in large quantities.

Where does the white sapote come from?

It is native to the central Mexican highlands, particularly the temperate regions of the Trans-Mexican Volcanic Belt. Its use is documented from pre-Hispanic times in sources such as Sahagún and Francisco Hernández. The name comes from the Nahuatl iztactzapotl (white sapote). Today it is grown mainly in the State of Mexico, Michoacán, Querétaro, Hidalgo, Guanajuato and Jalisco, as well as in California and parts of the Caribbean.
