8. Steaming the palm fruits

Palm fruits are extremely hard. When I picked at one with a fingernail, it was nearly impossible to scratch the surface. They must be softened before anything can be done. The first step is to ‘cook’ them for one hour with high-pressure, high-temperature steam (300 psi, 140 degrees Celsius). This picture shows a load of fruit that has just exited the steam chamber.
