On the other hand, the fruits of the cashew, almond and pistachio plants. You may have already heard that peanuts are not nuts. They are actually legumes and are members of the pea family. But did you know that cashew nuts, almonds, and several other common “culinary nuts” aren't real nuts either? To help us understand why this is the case, it is important to know what the definition of a true nut is.
Botanically, a nut is a dried fruit consisting of a hard shell that covers a single seed. Some examples of true nuts are acorns, chestnuts and hazelnuts. Botanically, a nut is a hard, single-seeded fruit that is indehiscent, meaning it doesn't open on its own at maturity. However, many commercial nuts do not meet the strict botanical definition.
A common feature of nuts is a hard outer shell, or shell. The shell is a natural package that protects the inner seed, generally of very high nutritional value, from animal predation. To overcome thick walnut shells, humans (and other primates) developed tools. The most primitive tools are rocks that chimpanzees use to break nuts.
Some scientists speculate that primitive nutcracker fragments could have been the first scraping and cutting tools used by early humans as they developed and improved technology. Anyway, while we were eating them, they asked us if we knew why you can't eat cashew nuts with shells. Actually, we had never thought about it. But, now that I think about it, you can get almonds, walnuts, pistachios, Brazil nuts, hazelnuts, peanuts, chestnuts, pine nuts, walnuts and even macadamia nuts in shell, but not cashew nuts.
. I remember when my uncle was chasing us (he has a lot of roosters and fighting cocks) when he sees us cooking cashew nuts. The Spanish brought Peruvian prostrate peanuts from Peru to the Philippines and southeastern China before 1600, and were later transported by Chinese merchants. The fruit is a nut similar to a drupe, with a dehiscent shell that breaks at maturity (usually from September to December) to reveal the elongated nut with a relatively thin shell.
From Greece, walnuts were introduced to Rome, where they were given the Latin name Jovis glans (“Jupiter's nut”), which was contracted to give the name of the genus Juglans. The coconut is light in relation to its volume, which allows it to float and be transported by water for long distances. The cultivation of hazelnuts in Italy is similar to that in Turkey, since it uses groups of multi-trunk seedlings, but with a more even spacing. Increasingly, hybrids between European and Japanese chestnuts are being cultivated commercially because the latter species is resistant to ink diseases.
The fruit is a four- to six-inch spherical pod with a thick outer shell that encloses twelve to twenty-four wedge-shaped nuts, each in its own rough, dark brown shell. The hard outer shell of a true nut doesn't open on its own, think walnuts, chestnuts, hazelnuts and acorns. Modern technology has provided worldwide access to a wide range of nut crops, while threatening the maintenance of the genetic and ethnobotanical diversity that produced them. As a valuable source of the necessities of life, sailors spread coconut throughout the Pacific, possibly as far as the Pacific coast of Central America and west to India and East Africa.
Since they grow in a pod, they are technically a legume, a family of plants that produce their fruits (often beans) in a pod and have more in common with snow peas than with real nuts. The thickness of the shell and the size of the nut were probably the two most important selection criteria for early walnut pickers, just as they are for modern walnut pickers. Perhaps exploring the variety of walnut crops in the context of their usefulness to humanity will contribute to improved management. .
