Answer 1

To store coriander root paste without spoilage, freeze it in small portions using ice cube trays or airtight containers. Alternatively, refrigerate it for up to a week by covering it with a layer of oil to prevent oxidation.

Detailed Explanation:

Coriander root paste, like many fresh herb pastes, is susceptible to spoilage due to its moisture content and the presence of enzymes that cause degradation. Proper storage is crucial to maintain its flavor and prevent the growth of mold or bacteria. Here's a breakdown of effective storage methods:

1. Freezing: This is the most effective long-term storage method.
   • Portioning: Divide the paste into small, usable portions. Ice cube trays are ideal for this. Once frozen, transfer the cubes to a freezer bag or airtight container.
   • Airtight Containers: Alternatively, use small, freezer-safe containers. Ensure minimal air space to prevent freezer burn.
   • Labeling: Always label the container with the date to keep track of freshness. Frozen coriander root paste can last for several months.
2. Refrigeration: For short-term storage (up to a week), refrigeration can work.
   • Oil Layer: Cover the paste with a thin layer of vegetable oil or olive oil. This creates a barrier against oxygen, which slows down oxidation and prevents discoloration.
   • Airtight Container: Store the paste in an airtight container in the refrigerator.

Pro Tip:

Before freezing, consider blanching the coriander roots briefly in boiling water for about 30 seconds, then immediately cooling them in ice water. This helps to deactivate enzymes that can degrade the flavor and color during freezing, resulting in a fresher-tasting paste when thawed.
