[TD="bgcolor: #FFFF99"]The most accurate method of testing the temperature of oil for deep-frying is a deep-fat thermometer. Make sure the bulb of your thermometer is completely immersed in the oil, but not touching the bottom of the pan. Otherwise, the reading could be affected. If you don’t have one, use the age-old method of dropping a square of bread into the hot oil; if it rises to the surface crackling and frying, the oil's hot enough. If it browns uniformly in:

  • 60 seconds, the temperature is 350 to 365°F
  • 40 seconds, the temperature is about 365 to 382°F
  • 20 seconds, the temperature is about 382 to 390°F

[TD="width: 628, bgcolor: #9999FF, colspan: 3"] Oils for Frying[/TD]
[/TR]
[TR]
[TD="width: 628, bgcolor: white, colspan: 3"] The oil or fat you use for deep-frying should have a high smoke point — the temperature to which it can be heated without smoking. Butter and margarine have low smoke points, so they aren’t good for frying but work for light sauteing. The best oils for deep-frying and high temperatures are refined safflower and sunflower oils, peanut, safflower and soy oils. Refined almond, avocado and cottonseed oil are also great if you can find and afford them, and canola oil is usually not a problem either.
Remove food particles from used deep-frying oil by straining it through a coffee filter, or a sieve or funnel lined with a double layer of cheesecloth. Cover, tightly seal and refrigerate strained oil; it can then be used one more time.
The temperature of the fat is all-important if the fat isn’t hot enough, food will absorb fat and be greasy, oils that can't take the heat will get too hot, and burn. The normal temperature range for frying is 325°F to 375°F, however, it'd quite likely that higher temperatures of 375°F to 400°F also are used. Most foods cook rapidly in the 325°F to 375°F range and develop a golden color, crisp texture and good flavor. High-temperature frying leads to thinner crusts and less oil absorption. Foods fried in this normal temperature range absorb 8 to 25 percent oil. Frying time is longer at lower temperatures. Frying at lower temperatures results in lighter color, less flavor development and increased oil absorption.[/TD]

[TD="width: 628, bgcolor: #9999FF, colspan: 3"] Refined Cooking Oils[/TD]
[/TR]
[TR]
[TD="width: 628, bgcolor: white, colspan: 3"] Refined Oils are extracted from clean oilseed / oil cakes by solvent extraction for further refining to produce clear oil, free from rancidity and foreign matter. These oils are used as medium cooking oils (225°F - 350°F), high cooking oils (350°F - 450°F), and deep-frying oils (greater than 450°F).
If the oil you buy is bland and pale, you can be certain that it has been fully refined, bleached, and deodorized. In essence, refined oils have negligible flavor and aroma which can be useful in delicately flavored dishes. Use for baking and sautéing, stir-fry and wok-fry, and oven cooking; to sear, brown, deep fry, fry and for tempura.

Canola (A US marketing name for rapeseed oil)​
[/TD]
[TD="width: 425, align: center"]
A light, golden-colored oil, similar to safflower oil. Low in saturated fat. Extracted from the seeds of a plant in the turnip family (the same plant as the vegetable broccoli rabe). Used in salads and cooking, mostly in the Mediterranean region and India; also used in margarine and blended vegetable oils. It has a mild flavor and aroma. It is most commonly available in a refined form. Its mild flavor and relatively high smoke point make refined canola oil a good all-purpose oil. Of all the oils, it has the least amount of saturated fat and is one of the least expensive.​

[/TR]
[TR]
[TD="width: 628, colspan: 3"] Unrefined cooking oils: These oils are typically called salad oils and are used for salad dressings, marinades, and sauces or light cooking oils (light sautes and low heat baking). As a general rule, they should not be cooked at high temperatures. Use for light sautéing, low-heat baking, pressure cooking, sauces and salads. However, safflower oil is the one unrefined oil that can become hot enough to reach the temperature necessary for deep-frying. Unrefined oil contains a full range of bioactive components that not only have healthful benefits and provide full-bodied flavor, but also make the oil more prone to oxidation. Using unrefined oils at temperatures above 320°F accelerates the oxidation of these oils.
Unrefined oils are processed by cold-pressed and expeller-pressed methods. Unrefined oils carry with them the true bouquet of olives, corn, sesame seeds, peanuts, soybeans, safflower, or whatever plant was the oil's original home. The strong flavors of unrefined oils can dominate whatever dish or baked good is made with them. Of course, strong flavor is not always a drawback; in some cases unrefined oils are used as flavoring agents. And, typically, where there is strong natural flavor and aroma, there is a higher amount of nutritional value. Best for medium heat temperature range: 212°F – 320°F.[/TD]

There are several types of olive oil. Most can be used interchangeably, but once you've learned to appreciate the flavor differences, you will be hard-pressed to use just any ol' olive oil. Almost all of the domestic varieties of olive oil are grown and harvested in California; imported varieties come from Italy, Greece, France, and Spain. The color and flavor can vary, depending on the type of olive, where it's grown, and under what conditions.
Olive oils are graded according to their acid content. The best olive oils are "cold-pressed," meaning that the oil is extracted by exerting pressure on the olives. This results in a naturally low acid content. Oils that have not been obtained through cold-pressing have been extracted through a chemical or steam process.
Extra virgin olive oil is the oil from the first pressing, with an acid content of 1 percent. All domestic extra virgin olive oil is cold-pressed; only about half of the imported extra virgins are cold-pressed. Extra virgin is considered the best olive oil because it's the most flavorful; it is also the most expensive. Virgin olive oil is also from the first pressing, but has a higher level of acidity, about 2 percent.
The flavor of extra virgin and virgin olive oils tends to break down at high heat, so use them when you want maximum olive flavor, such as in salad dressings, in soups and stews, and for dipping. Use other, less expensive olive oils for frying.
Fino olive oil is a blend of extra virgin and virgin. Oil that's labeled simply "olive oil" or "pure olive oil" is a blend of refined olive oil and virgin or extra virgin olive oil; it's higher in acid, making it better for frying due to its higher smoke point.
Olive oil should be stored in a cool, dark place, where it will keep for about six months. It also can be stored in the refrigerator; chilled olive oil turns cloudy, but that condition is easily reversed by returning the oil to room temperature.
Q. I'm trying to count calories and have been wondering: What is "light" olive oil?

A. Light olive oil is a relatively new variety of olive oil. Its light color and flavor result from a special filtration process. Light olive oil contains just as many calories and total fats, including the beneficial monounsaturated fats, as regular olive oil; "light" refers to its lighter color and flavor. Because of its light flavor, it is useful in baking and cooking dishes where regular olive oil would be too heavy or flavorful.
Light olive oil also has a higher smoke point than regular olive oil, meaning it can be used in frying over high heat.
Q. How do I store oil and for how long?

A. Oils will keep from three to six months when stored in a cool, dark place. If a cool spot is not available they should be refrigerated. Buy small quantities of oils that you use infrequently. Heat, light and time will turn oils rancid. A rancid oil will ruin any dish it is used in.
Q. What is the difference between extra virgin, virgin and just plain olive oils?

A. Olive oil is produced when tree-ripened olives are pressed. The best olive oils are extracted using a chemical-free process. They can be classified as extra-virgin or virgin. Both are cold-pressed oils from the first pressing of the olives.
Extra-virgin has a lower acidity and a full-bodied fruity flavor. It is the most expensive of olive oils. Use it when the fruity flavor will lend a pleasing note to foods, such as in salad dressings, for dipping bread and in vegetable dishes.
Products labeled olive oil are an all-purpose blend of olive oils. They are less expensive and blander in flavor, making them an economical choice for most uses. Light olive oil is olive oil that has been filtered to make it lighter in flavor. Filtering also increases its smoke point making it a good choice for sautéing and pan-frying.
Q. Can I substitute applesauce for oil in baking recipes? What is the correct ratio?

A. The recipes best suited for substituting applesauce in place of oil are recipes for quick breads, muffins, and other moist, cake-like baked goods. These products -- unlike cookies, which require the addition of butter for flavor and texture -- can effectively be made using applesauce without much sacrifice in taste.
If this is your first time making a low-fat version of a baking recipe, you may want to substitute only half the amount of oil with applesauce. Otherwise, substituting all of the oil with applesauce using a 1-to-1 ratio is perfectly acceptable.
When adding the liquid ingredients to the dry ingredients, do not overmix, as reduced-fat recipes have more of a tendency to become tough when baked. Baked goods made with applesauce may be slightly moister and denser than original oil-based recipes, but remember to bake until just done (when a toothpick inserted near the center of the product comes out clean). Dry, over-baked goods are never appetizing.







Types of Fats -

taken from http://www.webmd.com/food-recipes/tc/types-of-fats-topic-overview

Fats are nutrients that give you energy. Fats have 9 calories in each gram. Fats help in the absorption of fat-soluble vitamins A, D, E, and K. Fats are either saturated or unsaturated, and most foods with fat have both types. But usually there is more of one kind of fat than the other.
Saturated fat

Saturated fat is solid at room temperature, which is why it is also known as "solid fat." It is mostly in animal foods, such as milk, cheese, and meat. Poultry and fish have less saturated fat than red meat. Saturated fat is also in tropical oils, such as coconut oil, palm oil, and cocoa butter. You'll find tropical oils in many snacks and in nondairy foods, such as coffee creamers and whipped toppings. Foods made with butter, margarine, or shortening (cakes, cookies, and other desserts) have a lot of saturated fat. Saturated fat can raise your cholesterol. A healthy diet has less than 10% of daily calories from saturated fat.[SUP]1[/SUP]
Trans fat

This is a fat that has been changed by a process called hydrogenation. This process increases the shelf life of fat and makes the fat harder at room temperature. Harder fat makes crispier crackers and flakier pie crusts. Trans fat can raise your cholesterol, so eat as little trans fat as possible. You'll find it in:

  • Processed foods.
  • Snack foods, such as chips and crackers.
  • Cookies.
  • Some margarine and salad dressings.
  • Foods made with shortening and partially hydrogenated oils.
Unsaturated fat

Unsaturated fat is liquid at room temperature. It is mostly in oils from plants. If you eat unsaturated fat instead of saturated fat, it may help improve your cholesterol levels. Try to eat mostly unsaturated fats. Monounsaturated fat and polyunsaturated fat are types of unsaturated fat.

  • Monounsaturated fat: This fat is in vegetable oils, such as canola, olive, and peanut oils. Eating foods that are high in monounsaturated fats may help lower your "bad" LDL cholesterol. Monounsaturated fats may also keep "good" HDL cholesterol levels high. This may lower your risk of heart disease. But eating more unsaturated fat without cutting back on saturated fat may not lower your cholesterol.
  • Polyunsaturated fat: This type of fat is mainly in vegetable oils such as safflower, sunflower, sesame, soybean, and corn oils. Polyunsaturated fat is also the main fat found in seafood. Eating polyunsaturated fat in place of saturated fat may lower LDL cholesterol. The two types of polyunsaturated fats are omega-3 and omega-6 fatty acids.
    • Omega-3 fatty acids are found in foods from plants like soybean oil, canola oil, walnuts, and flaxseed.
