Why Make Your Own Cooking Oil?

Making your own oil gives you control over the ingredients and the skills to add to your survival tool belt. This means better flavor and no unexpected additives. Plus, during a disaster, store-bought oils may not be available so your only option is to make one yourself.

Cooking oils are basically fats that you use for frying, baking, and other culinary purposes. You can get them from plant-based sources like vegetables, nuts, and seeds. 

Oil can be used beyond its primary use for cooking. For instance, you can use it as a lubricant for squeaky hinges or tools that need a bit of smoothing.

If you’re exposed to harsh weather, oil can help protect your skin from drying out. Some oils, especially ones like tea tree, have antiseptic properties, making them useful for minor wounds.

Oil can also be a fuel source. It can power up lamps or even be used to create a temporary torch. And if communication is vital, oil can leave a mark or signal for help.

So next time you glance at that bottle, remember it’s more than just a cooking ingredient.

Ranging from sunflower to sesame, seed oils have been in culinary use for centuries, praised for their delicate taste and nutritional content.

They are derived from various types of seeds, such as flaxseeds, pumpkin seeds, and sesame seeds. These oils are rich in omega-3 fatty acids, which are essential for maintaining good heart health.

Two Methods on How To Make Oil At Home: Cold-Pressing vs. Hot-Pressing

While there are multiple ways to extract oil, cold-pressing and hot-pressing stand out as the most traditional. Both methods have their merits, with distinct results in terms of flavor and nutritional value.

Cold-Pressing

The cold-pressing method is often seen as the purist’s choice as it retains most of the nutrients. By avoiding heat, it ensures that the oil remains in its most natural state.

Cold pressed oils are made by crushing seeds or nuts to release the oil, then pressing them using a hydraulic or screw press.

Cold-pressed oils keep more nutrients like antioxidants, vitamins, and minerals because they are not heated to high temperatures, which can destroy these important compounds. 

Hot-Pressing

Hot-pressing uses heat to extract the oil from foods. Although using this method can lose some nutrients, it’s a faster process and produces a different flavor profile.

How To Make Vegetable Oil From Palm Oil

Learn the step-by-step process of converting palm oil into versatile vegetable oil. Palm oil, though controversial, remains a staple in many kitchens. By creating it at home, you can ensure a more sustainable and ethical approach to its production.

Here’s a simple method on how make it:

1. Harvest and prepare the palm fruits. They will have a reddish-orange hue.

2. Place the fruits in a pot, cover them with water, and boil for 30-60 minutes until they become soft and the skin starts to come off.

3. Once cooled, mash the fruits manually to separate the pulp from the kernels and the outer husk. Traditional methods involve pounding the fruits in large wooden mortars. You can also use a hand press or any device that can apply pressure. 

4. Add a little warm water to the mashed pulp and mix. The oil will begin to surface. You can then start scooping it out or pour the mixture through a sieve or cloth to separate the oil.

5. Place the collected oil in a pot and boil for about 10-15 minutes. This will help to separate any remaining water and contaminants from the oil. Once boiled, allow it to cool, and you will notice the oil will come to the surface while impurities settle at the bottom.

6. Skim off the pure oil from the top, ensuring not to collect the settled impurities. Transfer the oil to a clean, dry container and store it in a cool, dry place.

Keep in mind that this is a basic and traditional method. Large-scale production and refining processes are more complex and require more equipment.

If sourcing palm fruits, ensure they come from sustainable and responsible sources to mitigate environmental and ethical concerns.

How To Make Cooking Oil From Animal Fat

Turning to traditional methods, animal fats like lard and tallow can be transformed into cooking oils. These fats, when rendered, offer rich flavors reminiscent of age-old culinary traditions. Here’s a simple guide on how to render animal fat into oil:

1. Start by trimming any meat residues from the fat. This is important because meat can cause the fat to spoil or impart undesired flavors to the oil.

2. Cut the fat into small pieces, or even better, grind it. The smaller the pieces, the quicker and more efficiently the fat will render.

3. Melt the fat. Here are two ways on how to do it:

• Using a pot: Place the chopped fat into a large pot. Heat on the lowest setting. This process needs to be slow to ensure that the fat doesn’t burn. Stir occasionally.

• Using a slow cooker: If you have a slow cooker, it’s ideal for this purpose. Place the chopped fat in the cooker, set it on low, and let it melt slowly for several hours.

4. Allow the fat to simmer gently. As it renders, you’ll notice clear oil separating from the solid bits. This process can take several hours. Ensure that it doesn’t reach a boiling point to avoid burning the fat.

5. Once the fat is fully rendered (you’ll be left with clear oil and crispy solid bits known as “cracklings”), carefully strain the oil through a sieve or cheesecloth into your chosen container or jar, leaving the solids behind.

6. Allow the oil to cool down. Once cooled, it will solidify somewhat, especially if made from pork or beef fat. Store it in a cool, dry place or refrigerate. It can last for a long time if stored correctly.

Note:

• Beef fat, when rendered, is often referred to as “tallow.”
• Pork fat, when rendered, is called “lard.”
• Chicken fat is sometimes called “schmaltz,” especially in Jewish cuisine.

Remember to source your animal fats from trustworthy sources, preferably from pasture-raised animals, to ensure the best quality and flavor.

How to Refine Cooking Oil at Home

By understanding simple refining techniques, you can enhance the quality of your homemade oils, ensuring they remain fresh for longer. Refining oil can also elevate its purity.

1. Pour the oil through a coffee filter or a cheesecloth to remove any impurities or debris.
   
   
   
   
2. Add a small amount of citric acid to the oil and mix it thoroughly to neutralize it. Let the mixture sit for a few hours until the acid has neutralized any remaining free fatty acids.
   
   
   
   
3. Carefully pour the oil into a clean container, leaving any sediment or impurities behind.
   
   
   
   
4. Mix the oil with a small amount of activated charcoal or clay and heat it to about 120°C (248°F) for 20-30 minutes. This process will remove any remaining impurities and lighten the color of the oil.
   
   
   
   
5. Heat the oil to about 220°C (428°F) for 30 minutes to remove any remaining odor or flavor.
   
   
   
   
6. Allow the oil to cool and then filter it through a clean cheesecloth or coffee filter to remove any remaining impurities.
   
   
   
   
7. Transfer it to a clean, airtight container and store it in a cool, dark place.
   
   
   

Be cautious when heating oil as it can be dangerous. Always use appropriate safety measures and equipment.
