What are walnut biscuits?
Walnut biscuits are any tool used to break strong walnuts. There are two main varieties of walnut: English and black. English walnuts tend to have a softer shell that is relatively easy to burst using pocket, pliers of similar tools. Black varieties are usually much harder whose opening often requires complex levers or mechanized systems. Any tools that open the shells of these nuts can qualify as walnut biscuits, no matter how basic.
Walnuts are usually encountered by consumers in the form of a nut-like pieces of nuts ready for use. In this way, however, no nuts grow, because the meat is contained inside the hard shell of the nut. Walnuts are technically seeds and the shell is closed in a hard wooden pod on the tree. Mature nuts fall to the ground and then are either gathered by people who collect nuts, or eventually re -adjust themselves to the soil to hatch new trees.

As well as the shell protects the matrix from predators and environmental degradation, it also protects from easy human opening. Cracking of walnuts with bare hands is often very difficult, but eating or cooking with walnuts requires them to be open somehow. The walnut biscuits are specially designed to open the shells and reveal half of the nuts that can be easily removed and eaten.
The most basic walnut biscuits are slightly more than carved stands that hold the nuts in the end position. This allows accurate hit by hammer, mallet or other blunt object. Walnuts, like most types of nuts, burst mostly directly down their central line.
More advanced and commonly used walnut biscuits resemble pliers more than anything else. They join upstairsTwo metal handles, each usually with a central indentation of the size of the average diameter of the walnut. Place the walnut in the indentation and then pressed the nut to burst. The more a nut shell, the less the required force. This type of walnut crack usually works best for English walnuts.
black walnut biscuits usually include click and lever. Most of them are made of metal and requires the matrix to be placed between two screws or plates that must be progressively approaching and closer to each other until the built -up pressure bursts the shell.

English walnuts, despite their name, are not originally from England. They are indigenous in most Central Asia, especially in China, but quickly spread to the east, then to the west along the normal routes of ancient trade.
