Arugula, with its peppery bite and vibrant green color, is a beloved ingredient in salads, sandwiches, and even pasta dishes. But its delicate nature means it doesn’t last as long as other leafy greens. If you find yourself with an abundance of arugula from a farmer’s market haul or a garden harvest, knowing how to store it properly is crucial to prevent wilting and waste. While refrigeration is the go-to method for short-term storage, freezing arugula can be a game-changer for preserving its freshness and flavor for longer periods. This comprehensive guide will walk you through the best practices for freezing arugula, ensuring you can enjoy its unique taste whenever you crave it.
Understanding Arugula and its Freezing Potential
Arugula, also known as rocket, is a leafy green with a distinctive peppery flavor. It’s packed with nutrients, including vitamins A, C, and K, as well as antioxidants. While fresh arugula is best enjoyed immediately, freezing it can extend its shelf life significantly. However, it’s important to understand that freezing will alter the texture of the arugula, making it softer and more wilted compared to its fresh counterpart.
Freezing Impact on Texture and Flavor
Freezing causes ice crystals to form within the arugula cells, which can damage their cell walls. This leads to a change in texture, making the leaves softer and less crisp. The flavor of arugula also undergoes some changes during freezing. While the peppery bite remains, it may become slightly muted.
Best Uses for Frozen Arugula
Frozen arugula is best suited for applications where texture is not a primary concern. It works well in:
- Soups and stews
- Smoothies
- Sauces
- Pesto
It’s not ideal for salads or dishes where you want the arugula to maintain its crispness.
Preparing Arugula for Freezing
Proper preparation is key to ensuring your frozen arugula retains its best flavor and quality.
Washing and Drying
Start by thoroughly washing the arugula to remove any dirt or debris. Use cold water and gently massage the leaves to loosen any stuck particles. Drain the arugula in a colander and pat it dry with paper towels. Excess moisture can lead to freezer burn and affect the texture of the frozen arugula.
Blanching (Optional)
Blanching is a technique that involves briefly immersing the arugula in boiling water, then immediately plunging it into ice water. This process helps to preserve the color, flavor, and nutrients of the arugula. While blanching is optional, it can improve the quality of your frozen arugula.
Blanching Process:
- Bring a large pot of water to a rolling boil.
- Add the arugula to the boiling water and cook for 30 seconds to 1 minute, depending on the thickness of the leaves.
- Immediately transfer the arugula to a bowl of ice water to stop the cooking process.
- Drain the arugula and pat it dry thoroughly.
Freezing Arugula: Methods and Tips
Once your arugula is prepared, you can choose from several methods for freezing it.
Freezing in Ice Cube Trays
This method is ideal for small batches of arugula and allows for easy portion control.
Steps:
- Fill ice cube trays with prepared arugula leaves, leaving a small amount of space at the top.
- Pour water or a light broth over the arugula to cover the leaves completely.
- Freeze the trays until the cubes are solid.
- Transfer the frozen arugula cubes to a freezer-safe bag or container.
Freezing in Freezer Bags
For larger quantities of arugula, freezing in freezer bags is a more efficient option.
Steps:
- Spread a single layer of prepared arugula on a baking sheet lined with parchment paper.
- Freeze the arugula for 1-2 hours, or until solid.
- Transfer the frozen arugula leaves to a freezer-safe bag, removing as much air as possible.
- Store the bag in the freezer for up to 6 months.
Thawing and Using Frozen Arugula
Frozen arugula can be thawed and used in various recipes.
Thawing Methods
The best way to thaw frozen arugula is to transfer it from the freezer to the refrigerator overnight. This allows it to thaw slowly and evenly. You can also thaw it quickly by placing the frozen arugula in a bowl of cold water for 15-20 minutes.
Using Thawed Arugula
Once thawed, use frozen arugula within a few days. It’s best suited for applications where texture is not a primary concern, such as soups, stews, sauces, and smoothies.
Preserving Arugula: Other Storage Options
While freezing is a great way to extend the shelf life of arugula, there are other storage options for short-term preservation.
Refrigerator Storage
Refrigerator storage is the most common method for keeping arugula fresh for a few days.
Steps:
- Trim any damaged or wilted leaves.
- Place the arugula in a container lined with a paper towel to absorb excess moisture.
- Store the container in the crisper drawer of your refrigerator.
Storing Arugula in the Water
This method helps to keep arugula fresh for a longer period by mimicking its natural growing environment.
Steps:
- Trim any damaged or wilted leaves.
- Place the arugula in a glass or jar filled with about an inch of water.
- Cover the top of the jar with a plastic bag or wrap, leaving a small opening for air circulation.
- Store the jar in the refrigerator.
