Selecting and Storing Spinach
Selecting and storing spinach properly is essential to maintaining its freshness, flavor, and nutritional value. Whether you’re buying it from a local market or growing it in your garden, here’s a comprehensive guide on how to select and store spinach for optimal results:
1. Selecting Spinach:
Choose Fresh-Looking Leaves: Look for spinach leaves that are vibrant, crisp, and have a deep green color. Avoid leaves that appear yellowed, wilted, or have dark spots.
Size Matters: Smaller spinach leaves tend to be more tender and have a milder flavor. Baby spinach leaves are especially tender and great for salads.
Avoid Pre-Washed Spinach: While pre-washed spinach may seem convenient, it can sometimes have a shorter shelf life due to moisture. Opt for unwashed spinach and clean it at home just before use.
Check the Stems: The stems of spinach should be firm and not excessively woody. If the stems are tough and thick, it might indicate older spinach that could be less palatable.
2. Storing Spinach:
Store in the Refrigerator: Place your unwashed spinach in a plastic bag or an airtight container and store it in the refrigerator’s vegetable crisper drawer. Make sure the bag or container has some air circulation to prevent moisture buildup.
Don’t Wash Before Storage: Moisture can lead to spoilage, so avoid washing spinach before storing it. Washing before use is recommended to ensure cleanliness.
Use Paper Towels: To absorb excess moisture and maintain freshness, you can line the container with paper towels before placing the spinach inside.
Avoid High Humidity: Keep the humidity in the vegetable crisper relatively low, as high humidity can lead to wilted and slimy spinach leaves.
Use a Refrigerator Thermometer: Aim to keep your refrigerator at around 32 to 40°F (0 to 4°C) to slow down the deterioration of spinach and other perishable vegetables.

Spin or Pat Dry: After washing, use a salad spinner to remove excess water or gently pat the leaves dry with a clean kitchen towel.
4. Freezing Spinach:
If you have an abundance of spinach and want to extend its shelf life, consider freezing it:
Blanching: Blanch the spinach by dipping it in boiling water for a brief moment, then immediately transferring it to ice water to halt the cooking process.
Drain and Freeze: After blanching, drain the spinach thoroughly and pack it into airtight freezer bags or containers. Remove as much air as possible to prevent freezer burn.
Label and Date: Don’t forget to label the bags or containers with the date before placing them in the freezer. Frozen spinach can be stored for several months.
