Well Oiled: A Guide To Cooking Oils

 

I looked in my pantry last week and noted with amusement that I may not be well heeled, but I’m certainly well oiled!

My son is starting to show an interest in cooking, and he asked me a particularly good question, what are all these oils for? I tend to be an intuitive cook and I often go by taste or some stored piece of information that pops into my head when I’m cooking, eg. I just ‘know’ that peanut oil has a high smoke point and is great in Asian food. However, once I started reading up on the uses and benefits of various  cooking oils, I was delighted to find that there’s lots to play with.

Which oils shouldn’t be heated? Which oils are ideal for baking? Which can be used for frying foods?  Here’s a simple guide:

 

Coconut Oil

Extracted from mature coconuts,  coconut oil has a sweet, nutty flavour and a very distinctive ‘coconut’ scent, unless you use the odourless type.

Greatly resistant to oxidation at high heat, coconut oil is very suitable for high-heat cooking methods like frying.

Health Benefits

Pacific Islanders consider coconut oil to be the cure for all illness. The coconut palm is so highly valued by them as both a source of food and medicine that it is called "The Tree of Life”. Known for its high saturated fat content, coconut oil has been maligned as a ‘bad’ fat, however, this is now in dispute. Lauric acid is now believed to help prevent heart problems like high cholesterol and high blood pressure. The fatty acids in coconut oil metabolize differently and more easily, making it a good source of energy. It is easy to digest and may help in the healthy functioning of the thyroid and endocrine system.

Uses

All forms of cooking, especially frying eggs as it has a non-stick effect.

Add to smoothies for texture and healthy fat.

A great vegan alternative to butter.

 

Grapeseed Oil

Grapeseed oil is extracted from grape seeds, often as a by-product of winemaking! What’s not to love?

Fun fact: approximately 1 ton of grapes = 1 bottle of grapeseed oil.

Grapeseed oil has a high smoking point which makes it ideal for frying, sauteing and baking. Its light, neutral flavour means that it can be used as a base for infusions of garlic, rosemary and other herbs and spices.

Health Benefits

High in polyunsaturated fats such as Omega 6, grapeseed oil is also believed to help with raising healthy HDL cholesterol and lowering "bad" LDL cholesterol.

Rich in antioxidants and Vitamin E

Uses

Add to stews, curries and baked goods.

Perfect for deep frying and searing fish.

Perfect for salad dressings as it takes on the flavour of your strongest ingredient.

 

Hemp Seed Oil

Hemp seed oil, despite its Latin name  cannabis sativa, contains no THC, which is the psychoactive ingredient in cannabis. It is made by cold pressing hemp seeds and has a nutty, somewhat grassy flavour. This oil is not heat resistant or heat stable, so do not heat.

Health Benefits

Hemp seed oil is a great source of omega-3 and 6 essential fatty acids that may help reduce inflammation and helps lower blood pressure.

May be taken medicinally to boost the immune system and brain function.

Uses

Add to salads, juices, smoothies and vegetables.

Great as a salad dressing.

 

Olive Oil

Extracted from ripe olives that have been pressed,  olive oil has a strong flavour, sometimes buttery or peppery.  Extra virgin olive oil is the highest quality olive oil produced.

There has been much debate about heat and olive oil, but it has been found to be reasonably heat resistant and stable. It is not suitable for frying (too hot) nor ‘sweet’ baking, as it does have a strong flavour.

Health Benefits

Rich in Omega 3 fatty acids which are believed to help reduce bad LDL cholesterol.

High in oleic acid which reduces inflammation.

It has also been shown to lower blood pressure, which is one of the strongest risk factors for heart disease.

Uses

Grilling, sautéing and roasting.

Virgin olive oil is a healthy alternative to butter and margarine.

A key ingredient in Mediterranean cooking.

Its complex flavours make it perfect for salad dressings, vinaigrettes, dipping sauces, spreads, and marinades.

 

Peanut Oil 

Derived from peanuts, peanut oil has a delicious nutty flavour, that can be mild or strong depending on the processing.

It has an extremely high smoke point which makes it a good oil for frying.

Health Benefits

High in monounsaturated fats.

Contains Vitamin E.

High in antioxidants.

Uses

Frying and sauteing, typically used in Asian cooking.

Resistant to rancidity.

 

Sesame Oil

Extracted from sesame seeds,  sesame oil has a distinctively nutty flavour. It has a high smoke point and is very stable, making it ideal for frying.

Health Benefits

Rich in omega-3 essential fatty acids.

Source of vitamin E.

Uses

Perfect for stir- frys, salad dressings, sauces, and searing meat.

Refined or dark sesame oil is used mainly as flavouring, instead of as a cooking oil.

Sesame oil can be used as a daily nutritional supplement.  

 

Sweet Almond Oil

Extracted from almond kernels,  almond oil has a light, neutral, slightly nutty taste.

It has a high smoke point, and therefore suitable for frying, baking and cooking.

Health benefits

Rich source of vitamin E.

Contains monounsaturated and linoleic fatty acids, Omega 6 and Omega 9.

Uses

The slight nuttiness makes it perfect for baking biscuits and muffins.

Also great for end use eg. drizzle over salads, vegetables, dips, pasta etc.

 

Flaxseed Oil

An ideal Omega 3 supplement for those with fish allergies or who are vegan/vegetarian,  flaxseed oil is a rich source of  healthy fats, vitamins and minerals.

It has a low smoke point so should rather be used as a finishing oil or for low-heat cooking instead of for frying.

Health Benefits

One of the richest natural sources of Omega 3.

Source of lignans.

Uses

Drizzle over salads and cooked foods, or add to smoothies.

Can be taken on its own as a supplement.

 

Pumpkin Seed Oil

Pumpkin seed oil is cold pressed from pumpkin seeds and has a delicious nutty flavour.

It has a low smoke point so is not suitable for frying and cooking, but rather is best used as a finishing oil.

Try adding to ice cream for an intensely nutty flavour.

 

Siberian Pine Nut Oil

Siberian pine nut oil  is cold pressed from pine nuts grown in Northern forests. It has a soft nutty flavor and aroma.

Low smoke point so it is generally used for finishing rather than for cooking or frying.

Good for digestive disorders, including heartburn and gastritis, IBS and indigestion.

Source of vitamins, minerals, EFAs and Omegas 3 and 6.

Antioxidant.

Contains pinoletic acid which is an appetite suppressant and lowers cholesterol.

Health Benefits

Source of Omega 6, vitamins and fatty acid.

High in Vitamin E/

High oleic sunflower oil is boosted in monounsaturated fats too.
