What could be a more versatile food than a simple nut? For many, a nutless diet would lose much of its interest.
Nutless candy bars? Almost unthinkable. Ice cream toppings minus the crunch or a walnutless Waldorf salad?
No thanks.
Indeed, walnuts, macadamias, pistachios, almonds and pecans are a prevalent ingredient in the national diet.
Consider the English (also called Persian) walnut, a nut with origins dating back 7,000 years. Like many other horticultural treasures, walnuts first appeared in California with the arrival of Franciscan fathers from Spain and Mexico.
These days, most of the state's 195,000 acres of walnuts blanket central and northern California and account for 98 percent of the U.S. commercial crop, and two-thirds of the world's production.
And the news on nuts and their fat content may not be totally one-sided. A 1-ounce serving of walnuts contains 182 calories, and 17.6 grams of fat, which means 87 percent of the calories are from fat. Clearly, given the U.S. Surgeon General's guidelines of eating a total diet of 30 percent or less of calories from fat, this nut is on the fat side.
But according to a study conducted by researchers at Loma Linda University and published in the New England Journal of Medicine in March 1993, walnuts, when consumed in moderation (1 to 2 ounces) five or more times a week, and coupled with decreased consumption of fatty foods, were found to significantly lower the risk of heart attacks in men by decreasing levels of serum cholesterol. This is because some of a walnut's fat is composed of omega-3, which has cholesterol-lowering properties.
Almonds, like walnuts, are an important part of California's agricultural scene. Not only are almond trees beautiful to look at, but they are also one of the state's largest tree crops in terms of acreage and dollar value, providing all of America's needs, and over half the world's supply. Seven thousand farmers in California grow the gourmet nut.
Macadamias have become synonymous with Hawaii, but that state wasn't the first to consider commercial production of the elegant nut. The aborigines of eastern Australia knew of the nut long before the Western world elevated it to its superstar status.
In 1857, Ferdinand von Mueller, the first European botanist to identify a macadamia nut tree, named it for his friend John Macadam, a scientist living in Australia. A few specimens were brought over to Berkeley in the late 1890s, and only subsequently introduced to Hawaii as a commercial crop. Eventually, macadamias migrated south to San Diego County, where the handsome trees come in all shapes and sizes at places such as Cooper's Nut House in Fallbrook.
"We planted a few trees after a friend introduced us to the macadamia in the late '60s," says owner Tom Cooper, "and we've been adding ever since."
Jim Russell, for several years the president of the California Macadamia Nut Society, is also a pioneer in the field.
"Macadamia trees are very independent," he explains. "Every time you plant a seed you get another variety."
One of the drawbacks of fresh macadamias is that they are the hardest to crack. Indeed, after picking the brown-shelled nuts, the nut must be dried and cured, and then roasted for several hours in very low heat. Macadamias, like other nuts, are high in monounsaturated and polyunsaturated fats, and high in fiber and vitamin E. To ensure the most healthful results, Mr. Russell recommends using shelled, unsalted, raw California macadamias for cooking.
Unlike macadamias, pecans are relative newcomers to the California nut scene, thanks to growers like Irene Spensley and her husband Bob. What began as a hobby in the mid-'70s eventually led the Spensleys to establish a grove of 80 acres in Clovis, Calif., and to win first prize at the annual Western Pecan Growers Conference in 1991.
Another fairly recent import is the pistachio, which has taken to the state's climate and topography with a vengeance. Indeed, the Golden State has steadily been catching up to Iran, the world's leading producer of pistachios since 1976, date of the first commercial harvest in California. So much so, that California now ranks as the second-largest pistachio producer in the world.
The pistachio, a relative of the mango and the cashew nut, is native to the Middle East. The first ones to reach American shores from that area were originally dyed red by importers to camouflage defects in the shell. In their natural state, the small, .. tan-colored shells hang in delicate, grape-like clusters from the leafy medium-sized trees.
The following recipes, except for California Walnut Noodles, which is from the California Walnut Marketing Board, are from farmers.

Dolly's Medallions With Pistachio Butter
Makes 4 to 6 servings
2 pounds sliced turkey breast
2 tablespoons butter or margarine
1/2 cup dry white wine
1 cup whipping cream
1 cup chicken stock or chicken broth
freshly ground pepper
1/2 cup Cognac, optional
5 tablespoons Fiddyment pistachio butter or more, to taste
Lightly pound turkey medallions on flat surface or cutting board to tenderize them. Melt butter in large skillet over medium to high heat and saute medallions about 2 minutes on each side. Set aside and keep warm.
Add wine and deglaze pan drippings, stirring to incorporate brown bits. Boil until liquid is reduced by half. Add cream, stock, pepper to taste and Cognac. Boil, stirring, until sauce is again reduced by half. Remove from heat. Whisk in pistachio butter until blended. Add more pistachio butter if thicker sauce is desired.
Pour sauce over warm turkey medallions and serve immediately.
Tom Cooper's Molasses-Macadamia Nut Biscotti
Makes about 40 biscotti
3/4 cup butter, margarine or safflower oil
1 cup granulated sugar plus extra for logs
1/4 cup light molasses
1 egg
2 cups sifted flour
2 teaspoons baking soda
1/2 teaspoon ground cloves
1/2 teaspoon ground ginger
1 teaspoon ground cinnamon
1/2 teaspoon salt
1 cup raw macadamia nuts, coarsely chopped
1/2 cup raisins
Combine butter, granulated sugar, molasses and egg in large bowl and beat until smooth. Mix flour, baking soda, cloves, ginger, cinnamon and salt in separate bowl. Mix butter mixture with flour mixture until well combined. Fold in nuts and raisins.
On clean surface, divide dough into 2 equal parts. Shape each half into log about 2 inches in diameter and 12- to 14-inches long. Sprinkle some granulated sugar and any crumbled nut meats on piece of aluminum foil long enough to hold log. Roll each log back and forth on foil until covered with mixture. Set logs on rimless, ungreased baking sheet. Bake at 350 degrees until crust forms, about 16 minutes. (Logs will flatten considerably as they bake.)
Remove logs from oven and cool a few minutes. (They will harden as they cool.) Cut logs with very sharp knife into diagonal slices 1 1/2 -inches wide. Biscotti will be about 3 inches long. Place on rack to cool completely. Store in airtight container.
NOTES ON NUTS
Nuts contain oils, and thus, can turn rancid. To preserve them for a long time, store them in an airtight container in a cool, dry place or freeze them for up to a year. Raw, unshelled nuts keep better.
Toasting nuts brings out their rich flavor. Toast them on top of the stove in a nonstick skillet, tossing them around until they turn golden brown, or place them in a single layer on a nonstick baking sheet, and bake them at 350 degrees 3 to 5 minutes, stirring often and watching carefully so they don't burn.
