It is the same as the vegetable-based cooking fat called Copha, except there are two varieties of Palmin: one comes in a tub, which is almost spreadable, and the other comes in a block like Copha.
The blocks come in 250g (1/2 pound) portions.
Palmin is available in many European delicatessens in North America.
