Borlotti Beans or Rose Cocoa Beans. Borlotti Beans are streaked with rose or crimson, and are better when pale of colour. Very popular in Italy.
Borlotti Beans are sweet and have a soft texture.
In Italy, you can purchase borlotti beans fresh and they can be prepared much like broad beans, but cooked for somewhat longer. However, usually you will need to use either dried or tinned. If preparing from dried, soak first overnight and boil the drained beans for 45 minutes until tender.
Beans last for a good length of time, but do toughen with age, so buy in smallish quantities. If you buy in bulk, check for dirt and insects as these are not uncommon and should be anticipated. Store somewhere dark and cool, and free from potential insect contamination. Tins are a godsend to any cook as they are quick to prepare and long lasting.
