Edible nuts come from the forest or orchard to the dinner table through various routes. Some are imported. Brazil nuts, for example, come from a tropical tree. However, most nut trees are planted in orchards, with Kentucky being a major area. Soy and peanuts are generally grown in the midwest. As a reminder, neither of these are nuts, and pine nuts are, of course, harvested from certain pine trees. They can even be harvested from the wild.
Nuts may be distributed as raw or roasted, dried or fresh, either as a single type or in a mixed bag. Gourmet gift baskets may contain packets of nuts. Peanuts for snacking may be roasted with honey. In this case, they are shelled in a shelling facility, although both bulk and retail nuts may be sold whole to be cracked at home. Many of these companies also sell edible seeds.
The use of nuts as ingredients is common. Manufacturers of peanut butter or almond milk use nuts as a raw material to create their product. These companies and those who make praline or brittle, commonly from almonds or macadamia nuts, require workers with some expertise in food production. Pistachios are often used to flavor ice cream.
Distributors also require knowledgeable salespeople. There are different uses for walnuts and brazil nuts, and particular recipes may even require cashews or pecans. A nut salesperson needs to know the difference between macadamias and walnuts. Some companies may distribute recipes with their products or post them on their web site.
Of course, people with a yard or garden may choose to grow their own nuts rather than buy them. For those who do not, nuts are easily obtained from grocery and health food stores.
