How to Store Arugula

Introduction

Arugula, also known as rocket or roquette, is a leafy green vegetable that has gained popularity for its peppery flavor and nutritional benefits. This versatile ingredient is commonly used in salads, sandwiches, and as a garnish. However, to preserve its freshness and flavor, proper storage techniques are essential. This article delves into the various aspects of arugula, focusing on how to store it effectively while addressing its history, production, quality, and common misconceptions.

What Is Arugula?

Arugula (Eruca sativa) is a cruciferous vegetable belonging to the Brassicaceae family, which also includes cabbage, broccoli, and mustard greens. It is characterized by its lobed, dark green leaves and distinctive peppery taste, which intensifies with age. Arugula is often enjoyed raw but can also be lightly cooked, making it a versatile addition to a variety of dishes. It is rich in vitamins A, C, and K, as well as minerals like calcium and potassium.

History and Origins

Arugula has a rich history that dates back to ancient civilizations. Originally cultivated in the Mediterranean region, it was valued not just for its flavor but also for its medicinal properties. The Romans used arugula as an aphrodisiac, and it found its way into various traditional dishes. Over time, arugula spread to different parts of Europe and eventually to the Americas, where it has become a staple in modern cuisine.

Production and Processing

Arugula grows best in cool temperatures and can be planted in both spring and fall. It thrives in well-drained soil and requires moderate watering. The growth cycle is relatively short, typically taking about 40 to 50 days from seed to harvest. After harvesting, arugula is generally processed minimally, often being washed and packaged for retail.

Commercial production of arugula has expanded significantly, particularly in the United States, where it is grown primarily in California. Organic farming practices have become increasingly popular, as consumers demand higher-quality, pesticide-free produce.

Quality and Grading

The quality of arugula can be assessed based on its color, texture, and smell. Fresh arugula should have vibrant green leaves that are free from yellowing or wilting. The leaves should feel crisp and firm to the touch, indicating that they are fresh. An unpleasant odor or sliminess can be signs of deterioration.

In commercial settings, arugula is often graded based on these characteristics, with higher grades reserved for produce that meets strict quality standards.

Buying Considerations

When purchasing arugula, consider the following factors:

1. Freshness: Look for vibrant green leaves that are crisp and free from blemishes or brown spots.

2. Packaging: If buying pre-packaged arugula, check the packaging for expiration dates and ensure it is tightly sealed to prevent moisture loss.

3. Organic vs. Conventional: Opt for organic arugula if possible, as it is typically grown without synthetic pesticides and fertilizers.

4. Local vs. Imported: Local produce is often fresher than imported options, as it has not traveled long distances.

5. Seasonality: Arugula is generally available year-round, but its peak season is in the cooler months. Buying in season can yield better flavor and quality.

Uses and Applications

Arugula is a versatile ingredient used in various culinary applications. Its peppery flavor makes it an excellent addition to salads, where it can be the star or complement other ingredients. It can also be used in sandwiches, pestos, and as a topping for pizzas. Additionally, arugula can be sautéed or added to soups and stews, though cooking may mellow its distinctive taste.

Storage and Shelf Life

Proper storage is crucial to maintaining the freshness and quality of arugula. Here are some effective storage methods:

1. Refrigeration

  • Preparation: Before storing, remove any damaged or wilted leaves from the bunch. This helps prevent decay from spreading to healthy leaves.
  • Wrapping: Wrap arugula in a damp paper towel to retain moisture. Place it in a perforated plastic bag or a container with ventilation to allow for air circulation.
  • Placement: Store the wrapped arugula in the crisper drawer of your refrigerator. This section typically maintains a higher humidity level, which is beneficial for leafy greens.

    • 2. Freezing

    While freezing arugula is not commonly recommended due to its texture, it can be done if necessary:

  • Blanching: Briefly blanch the arugula leaves in boiling water for about 30 seconds. This helps preserve color and flavor.
  • Cooling: Immediately transfer the blanched arugula to ice water to stop the cooking process.
  • Drying and Packaging: Pat the leaves dry and place them in airtight freezer bags. Remove as much air as possible before sealing.
  • Storage: Store the bags in the freezer. Frozen arugula is best used in cooked dishes, as its texture will change once thawed.

3. Storage Duration

When stored properly, fresh arugula can last up to a week in the refrigerator. However, its quality may begin to decline after a few days. Frozen arugula can last several months, but for the best flavor, it is advisable to use it within three to six months.

Common Misconceptions

1. Arugula is Only a Salad Green: While arugula is often used in salads, it is a versatile ingredient that can be used in a variety of dishes, both raw and cooked.

2. Arugula Must Always Be Fresh: While fresh arugula offers the best flavor and texture, frozen arugula can still be used effectively in cooked dishes.

3. All Arugula Tastes the Same: The flavor of arugula can vary based on its age and growing conditions. Younger leaves tend to be milder, while older leaves can be more pungent.

4. Washing Before Storage is Necessary: It’s generally better to wash arugula just before use rather than before storage, as excess moisture can lead to decay.
