Olive oil (with recipe)


            The gnarled olive tree has been the purveyor of health and wealth since times of great antiquity. The Mediterranean shores were its earliest home, and in Homeric times olive oil was the luxury only of the very wealth, who used it mainly as an ointment after bathing. Later in Italy, every single part of the olive tree found its use: the olive itself, ripe or unripe, as a delectable item of food; the oil as an adjunct to cooking; the oil as fuel for lamps; the oil as applied to the skin; the leaves and bark as a tonic tea; the resinous olive “gum” as a medicinal and perfume. During the heyday of the Roman Empire, a prescription for the pleasant life called for “wine within and olive oil without”.

            Olive culture has now spread to many parts of the earth, and California, China, and Australia have joined North Africa, Spain, France, Italy, and Greece as producers of olive oil. Italy remains, however, the high priestess of the olive, and little can equal the highest quality pure Italian olive oil. Olive oil varies tremendously in quality, depending on the type of olive used, the methods of refining, and whether it has been mixed with other cheaper oils. The term “virgin” is so widely and loosely applied that it no longer is any indication of quality; originally it meant that an oil was from the first pressing of the fruit, as opposed to the second or third pressings, whose oil is of inferior quality. Olive oil when unrefined has a greenish tinge and a very pungent flavor. It is preferred in certain areas to the refined oil, and certainly its healthful qualities are more intact – but you might have to cultivate a liking for the strong taste.

            Olive oil oxidizes less rapidly than other oils; therefore, it does not need to be refrigerated to prevent rancidity. It is somewhat more saturated than certain other vegetable oils, but many a centenarian Italian has attributed his long life to the virtues of olive oil – and we side with the centenarians over the saturationists, and cherish our pure olive oil!

            Use olive oil in cooking as you would butter. For a truly gourmet flavor, use half olive oil and half butter when sautéing or starting a sauce. Try sprinkling olive oil and lemon juice over hot vegetables, rather than the customary butter – it’s delicious, it’s healthy, and what is left over is great as a cold salad. Olive oil is incomparable in salad dressing. Here follows the way to dress a salad.

SALAD DRESSING

Have on your table:
A vial of pure olive oil
Sea salt
A vial of wine vinegar
A pepper grinder
A large bowl, no more than half-filled with freshly prepared salad

1.      Pour olive oil over the salad. (A quart of salad will take about 3 tablespoons oil, but this is variable; you want enough to coat all parts of the salad with a thin layer of oil, with none left in the bottom of the bowl). Toss the oil into the salad until everything is well coated.
2.      Then put ½ - 1 teaspoon salt in a large spoon and fill spoon with vinegar (ratio of vinegar to oil should be about 1 to 3). Stir gently until the salt is dissolved in the vinegar, then sprinkle over the salad; add more vinegar if necessary. Grind pepper over salad. Toss well and serve.
3.      Salad should be served either before (health food style) or after (European style), never with the meal. With this method of preparing salad, the nutrients are sealed in by the oil so that the vinegar and salt cannot leach them out. The salad stays crisper, and salt, vinegar, and pepper are evenly distributed throughout rather than being deposited in clumps. Make a ritual of your salads!

Oil, Vegetable (with recipe)


            Vegetable oils occupy an important position in nutrition; it therefore pays to obtain the best quality available, even if it is somewhat expensive. How to recognize the “best” is a little tricky, but with a few basic facts under your belt you can surmount the problem with ease. First step: try to avoid commercial big-name brands. These oils are all extracted by use of petroleum-based solvents, and there is real danger of carcinogenic residues remaining in the oil. They are also exposed to excessively high heats and refining processes, which leave them odorless, tasteless, colorless – and unnaturally healthless. They are also permeated with preservatives. Stay away from them.

            What you should aim for is a pressed oil in crude or relatively unrefined state.  Pressed oil are obtained by use of hydraulic or expeller presses. The oil is forced by pressure out of the nut or seed or grain rather than being extracted chemically by use of solvents. Crude or unrefined oils are exposed to various degrees of filtration rather than to refinement by means of caustic chemicals.

            Cast a wary eye on labels. Question the term “cold-pressed”. All oil-giving substances (with the exception of olives and sesame seeds) must be exposed to a certain amount of heat before they will yield their oil. Question the term “unrefined”. A truly unrefined oil is dark in color, thick in substance, and pungent in taste – and does not appeal to all palates. Question the term “virgin” (as in olive oil). As an indication of quality it is absolutely meaningless, for there are no standards governing its usage.

            All properly processed vegetable oils provide excellent sources of unsaturated essential fatty acids, vitamin E, and lecithin. The type of oil you choose depends on your own taste or intention. Peanut oil is good for frying, and many Asian recipes blossom with it. Olive oil is unsurpassable for salads, and Italian dishes would lapse into lethargy without it. Corn, sunflower, and safflower oils are all highly unsaturated and good for general use. Then there are sesame, avocado, walnut…Experiment!

            Always refrigerate vegetable oil after opening so that it will not become rancid. It will keep longer if it is in a dark container, for the oil deteriorates more rapidly when exposed to light. Vegetable oils can (and should) be successfully substituted for hydrogenated fats such as margarine, shortening, and lard in many recipes. Here, for instance, in an easy-to-make piecrust prepared with pressed vegetable oil.

PIE CRUST

1/3 cup ice water
2 cups whole wheat pastry flour
1 teaspoon salt
1/3 cup cold butter
1/3 cup cold olive oil

1.      In a small bowl place an ice cube and about 1/3 cup water.
2.      Into a large bowl, sift flour and salt. Add cold butter, cut into small pieces. With fingers quickly mix with flour until butter and flour form pea-size lumps. Measure out 1/3 cup ice water and add 1/3 cup cold oil into same container. Pour all at once into dough and mix quickly with fingers, forming into a ball. Roll out immediately or refrigerate for later use.
3.      Makes enough pastry for one double-crust pie or two single crusts.
4.      Note: In order to have a flaky crust, the butter must not get too soft. Therefore work quickly; if at any point the butter seems to melt, refrigerate for a few minutes, then continue the recipe.
