To start, it’s important to handle rainbow chard with care, as it can easily become wilted or bruised.

Immediately after purchase or harvesting, prepare chard for storage by removing any ties or bands which can damage the stalks and leaves.

If you notice any damaged or decayed parts, trim them off before storage, as they can cause the rest of the chard to decline in quality more quickly.

When storing chard, your refrigerator is the best tool at your disposal.

You can extend the freshness of rainbow chard for several days by wrapping the stalks in a damp paper towel or cloth to provide the necessary moisture.

Then, place the wrapped chard in an open or perforated plastic bag in the crisper drawer of your refrigerator.

This method helps to create an environment with the right humidity and temperature to keep your chard crisp and vibrant for up to a week.

Selecting Rainbow Chard for Storage

Before storing your rainbow chard, it’s important to select the freshest bunches and to understand which leaves are best for long-term storage.

Identifying Fresh Chard

To ensure you’re selecting the freshest rainbow chard, look for leaves that are vibrant in color with no signs of wilting or discolored edges.

Each leaf should feel tender and appear glossy, without any slimy patches which can indicate spoilage.

The stems should be firm, crunchy, and brightly colored, ranging from white to yellow, pink, red, or purple, characteristic of rainbow chard. Avoid any bunches with stems that appear limp or dried out.

Choosing Leaves for Long-Term Storage

For the best results in long-term storage, prioritize leaves that are:

  • Consistently colored: Leaves should have uniform coloration without browning or yellowing spots.
  • Free of damage: Choose leaves without tears, holes, or bruises.
  • Medium in size: Extremely large leaves may not store as well, while the medium-sized ones tend to be more tender and store better.

Initial Preparation Before Storing

Before you store your rainbow chard, it’s essential to ensure it’s clean and dry. This initial preparation is key to maintaining the freshness and longevity of the chard in storage.

Cleaning Chard

Begin by thoroughly rinsing the rainbow chard leaves under cool running water to remove any dirt and grit.

  • Step 1: Separate the leaves from the stalks.
  • Step 2: Hold each leaf under the water, gently rubbing to dislodge any debris.
  • Step 3: Use a colander to make this process easier, ensuring a good rinse.

Drying the Leaves

After cleaning, it’s vital to dry the leaves to prevent moisture buildup, which can lead to rot.

  1. Pat the chard dry with a clean cloth or paper towels to absorb excess water.
  2. To finalize drying, lay the leaves on a clean surface and cover them with another damp paper towel. This secures enough moisture to keep the chard from dehydrating without being overly wet.

Storing Fresh Chard in the Refrigerator

When storing fresh chard, maintaining the right balance of humidity and temperature is crucial to keep the leaves crisp and full of flavor. Here’s how you can achieve this balance using different methods within your refrigerator.

Using Plastic Bags for Refrigeration

Wrap your chard leaves in a damp paper towel to ensure they retain moisture.

Then, place the wrapped chard in an open or perforated plastic bag. This allows for some air circulation to prevent rot, while the damp towel provides the necessary humidity.

Store the bag in the refrigerator’s main compartment to stay fresh.

Utilizing Airtight Containers

If you prefer using containers, line an airtight container with paper towels both underneath and above the chard leaves.

The paper towels will absorb any excess moisture, preventing sogginess.

Ensure the container is not fully sealed; a small opening allows for the right amount of airflow to prevent condensation build-up, which can lead to faster spoilage.

Crisper Drawer: Optimizing Humidity

The crisper drawer is designed to maintain an optimal level of humidity for leafy greens like chard.

Before placing your chard in the crisper drawer, loosely wrap it in a plastic bag or a damp cloth to provide moisture.

Adjust the crisper settings to a moderate level to prevent the chard from wilting or becoming too moist, which could shorten its shelf life.

Freezing Chard for Extended Freshness
