The corossolier is a close relative to the sweep-sop. In terms of size, the fruit is substantially larger than the sweet-sop with some fruits weighing as much as 1.5 kg. The peel is smoother with tiny spikes (more like bumps). These spikes turn black as the fruit ripens.
The corossolier has less seeds than the sweetsop and the meat is more firm, almost chewy. In general, the fruit has a sweet and sour taste. In Vietnam, the corrosolier is blended with condensed milk and ice to make a delicious fruit drink. During the Tet season, the corossolier is preserved with sugar to make a candy-like treat called jam. Learn How to make Vietnamese jam.
