Caja (Hog Plum) in gelato

Caja (Spondias mombin), known in English as hog plum or yellow mombin, is a tart, aromatic tropical fruit from the Anacardiaceae family. In gelato it is used as a frozen pulp to build an intensely fragrant, high-acid sorbet base, contributing mostly water and modest, reducing-sugar-rich solids.

How to use it in gelato

Caja is used as a fruit pulp for sorbets and fruit gelato, valued for a sharp citrus-tropical aroma. Its sugars are dominated by glucose and fructose (about 79% reducing sugars), giving a high per-sugar antifreeze coefficient (PAC ~1.7 in dry base) so it lowers freezing point efficiently per gram of sugar. Because total sugar and solids are low and acidity is very high (pH ~2.3-3.3), recipes need substantial added sucrose plus dextrose to reach both sweetness and body; a stabiliser helps offset the thin, watery pulp. Its strong citric acid also depresses freezing point beyond the sugar calculation, so keep an eye on final PAC.

Origin & background

Spondias mombin is native to the tropical Americas and has been naturalised across West Africa and Asia; in Brazil it is called caja and is documented in the national food composition table TBCA-USP and studied by Embrapa. English names hog plum and yellow mombin reflect its plum-like drupe and yellow-orange ripe skin.
