Steps in preparing arugula for freezing

1. Wash salad rocket with water

Wash the leafy greens with water to eliminate the bacteria that may be living on the surface of the leaves. It’s essential that you make sure that every leaf is free of any debris to further reduce the possibility of early quality decline. 

To take your bacteria elimination process up a notch, add vinegar to the water you’re using to wash arugula. The acidity of vinegar targets the cell membrane of bacteria living on the leaves' surface, completely killing it. 

2. Pat dry with a damp towel

After washing them, make sure to spread the leaves on a tray or a clean surface. Gently pat the leaves with a damp towel or a paper napkin to remove the remaining water on them. The leaves must be completely dry for the fourth step to work its magic. 

3. Chop arugula leaves

Chop the leaves in sizes of your preference. Place the chopped arugula in a pie tin or an ice cube tray. Why should you chop the arugula leaves? Because their length can be obtrusive when you proceed to the next step. 

4. Soak in olive oil

Pour in the olive oil in the pie tin or ice cube tray filled with arugula leaves. Ensure the leaves are completely immersed in the oil to keep the flavor of arugula sealed even if a long time passes.

Why should you use olive oil and not other varieties of oils? Olive oil has been used for thousands of years in preserving food, especially in the countries surrounding the Mediterranean. This particular oil acts as a seal that keeps the flavor in food ingredients like arugula. Plus, it also helps in extending the shelf life of the salad and reinforces the health benefits found in preserved foods. 

5. Pre-freeze olive oil-soaked arugula

Once the arugula leaves are immersed in olive oil, put the pie tin or ice cube tray in the freezer and wait 2 to 3 hours or until it has frozen completely. 

Steps in packaging arugula for freezing

1. Put frozen arugula in containers

Put the pre-frozen arugula in airtight containers or freezer bags that you can vacuum seal. 

2. Freeze

Finally, pop the containers in the freezer, and you now have a frozen stock of arugula when you need it. 

You can keep the arugula in the freezer indefinitely without worrying about its original flavor wearing away.
