How to Make Rosemary Oil

How to Make Rosemary Oil

Rosemary oil is a sought-after infused oil extensively utilized in both culinary preparations and various beauty treatments. If you desire a prompt method to create your own rosemary oil, simply heat a few sprigs of fresh rosemary in your preferred oil. 

It is crucial to note that this oil should be consumed or utilized within a week to prevent potential spoilage. Alternatively, for a longer-lasting option, dried rosemary can be employed to craft an oil with an extended shelf life. 

By combining dried rosemary with your chosen oil in a canning jar and placing it in a sunlit area, you can gradually infuse the flavors into a delectable edible oil. This technique can be applied using either prepackaged dried rosemary or homemade dried rosemary of your own making.

Use Fresh Rosemary

Follow These Steps:

Wash the rosemary: 

Rinse a few sprigs of fresh rosemary with cold, running water to remove any dirt and debris. Remove the leaves from the stem and measure approximately one cup of leaves. You can discard any leftover rosemary leaves or set them aside for other recipes.

Prepare the oil: 

Take a small saucepan and pour two cups of oil into it. Olive oil is a popular choice due to its flavor, cooking uses, and cosmetic applications. However, if you plan to use the oil solely for beauty purposes, you can use jojoba oil or sweet almond oil. Remember that jojoba oil and sweet almond oil should not be consumed or used in cooking.

Heat the rosemary in the oil: 

Add the rosemary sprigs to the saucepan and place it over low heat on the stove. Heat the rosemary for five to ten minutes while stirring constantly. As the oil warms up, it will release the aroma of rosemary. If the oil starts to bubble excessively around the rosemary, reduce the heat and continue stirring.

Strain and cool the oil: 

Set a metal colander in a large metal bowl. Pour the oil mixture into the colander to separate the rosemary pieces from the oil. Discard the leftover rosemary pieces and allow the oil to cool in the bowl. Alternatively, you can use metal strainers or cheesecloths to strain the oil, but make sure the oil has cooled before using these tools.

Bottle the oil: 

Once the oil has cooled to room temperature, pour it into a clean bottle. Remember to label the bottle with the bottling date and the ingredients used. Avoid adding a sprig of rosemary to the bottle for decorative purposes, as it can promote the growth of harmful bacteria in the oil.

Refrigerate the oil: 

Oils infused with fresh herbs should be refrigerated and used within a week. This will prevent the growth of any harmful bacteria that could cause the oil to spoil. If you are giving the oil as a gift, include a “use by” date on the label.

To Infuse Oil With Dried Rosemary

Follow These Steps:

Sanitize a canning jar: 

Fill a large, deep pot with water and heat it over medium-high heat. Once the water boils, use tongs to place the canning jar in the water. Allow the jar to boil for ten minutes, effectively eliminating any harmful bacteria that could compromise the quality of your rosemary oil. Remember, the lid does not need to be boiled. Instead, wash it with soap and water, and let it air dry. If you have a boiling-water canner, you can use it to sterilize the canning jar, following the instructions provided by the manufacturer.

Place dried rosemary in the jar: 

If you have dried your own rosemary, put three to four sprigs into the jar. In the case of prepackaged dried rosemary, add a generous tablespoon to the canning jar. Avoid using fresh, undried rosemary, as it can cause the oil to become rancid and potentially harbor harmful Botulism bacteria.

Pour oil over the rosemary: 

Fill the jar with olive oil, ensuring that the rosemary is fully submerged. Leave about half an inch (1.2 centimeters) of space at the top of the jar. If needed, use a clean spoon to gently press the dried rosemary into the oil. Coconut oil can also be used as an alternative to olive oil.

Place the jar in the sun: Screw the lid onto the canning jar and position it in a sunny location. Leave it undisturbed for two weeks. During this time, the oil will gradually warm up and infuse with the delightful flavors of rosemary. After the two-week period, your that oil will be ready for use.

Strain the oil: 

Take a large metal bowl and line it with a cheesecloth, ensuring the edges hang over the sides. Empty the contents of the canning jar into the cheesecloth. Gather the cheesecloth into a bundle and exert pressure over the bowl to extract the oil from the small pieces of dried that. You can use clean hands to squeeze the cheesecloth. Discard the leftover pieces of rosemary.

Store the oil by pouring the strained olive oil back into the canning jar and replacing the lid. If desired, you can add a sprig of dried this to the oil for decorative purposes. Oils infused with dried herbs have a shelf life of approximately one year. If you decide to transfer the oil to a different jar, make sure to sterilize the new jar beforehand.

To Dry Fresh Rosemary

Follow These Steps:

Wash the fresh rosemary: 

If you have access to a this bush or have purchased fresh rosemary from the grocery store, wash the sprigs under running water to remove any dirt and debris. Gently pat the rosemary with a paper towel to remove excess water or use a salad spinner if available. For making one canning jar’s worth of that oil, you will need around three to four sprigs of this. Keep in mind that dried rosemary has a long shelf life, so you can dry as much as you desire, even if you don’t plan to use it all for this oil.

Place the rosemary on a baking sheet:

Line a large baking sheet with a piece of parchment paper, ensuring that it covers the entire sheet. Then, arrange the rosemary sprigs on the baking sheet in a single layer. It’s important not to overcrowd the rosemary, as proper drying requires adequate air circulation.

Dry the fresh rosemary in the oven: 

Preheat your oven to the lowest setting for about ten minutes. Once preheated, place the baking sheet with the rosemary in the oven. Allow the this to bake for approximately two to four hours. The drying time may vary based on the thickness and moisture content of the this sprigs. When the rosemary is fully dried, it should crumble easily between your fingers.

Let the sprigs cool completely: 

Once the rosemary is done drying, remove the baking sheet from the oven. Allow the sprigs to cool completely before using them to make this oil or storing them for future use. This cooling period ensures that the rosemary is at room temperature and ready for further processing.
