What You’ll Need
- Fresh artichokes
- A vacuum sealing machine
- Plastic vacuum-sealing bags
- Sharp knife or kitchen shears
- Lemon juice (optional)
Step 1: Prep Work
Start by selecting fresh artichokes that are firm and have vibrant green leaves. Wash the artichokes thoroughly, removing any dirt or debris. Then, trim the stems to about an inch in length, ensuring they are clean and free from blemishes or bruises.
Step 2: Remove the Tough Outer Leaves
Gently pull off the outermost layer of tough leaves until you reach the more tender ones beneath. Repeat this process until you have removed enough leaves to expose the artichoke’s pale yellow center, known as the heart.
Step 3: Preparation for Vacuum-Sealing
If desired, immerse the trimmed artichokes in a bowl of water mixed with lemon juice to prevent them from browning. While this step is optional, it can help maintain their color and freshness.
Step 4: Blanch the Artichokes
Blanching ensures that your artichokes retain their flavor, color, and texture. Bring a pot of water to a boil and carefully add the artichokes. Allow them to cook for about 7-8 minutes until they become slightly tender. Once done, transfer them immediately to a bowl of ice water to halt the cooking process.
Step 5: Vacuum-Sealing the Artichokes
Dry the blanched artichokes gently with a clean kitchen towel. It’s time to seal them in a vacuum-sealing bag. Place the artichokes in a single layer inside the bag, leaving enough space between each one. Ensure the bag is properly sealed according to your vacuum sealing machine’s instructions.
Step 6: Freezing or Refrigerating
Depending on when you plan to use your artichokes, you can either freeze or refrigerate them. If freezing, lay the sealed bags flat on a tray and place them in the freezer until fully frozen. Once frozen, you can stack them neatly to save space. If refrigerating, put the sealed bags directly into the refrigerator.
Step 7: Enjoying Your Vacuum-Preserved Artichokes
When you’re ready to use your vacuum-sealed artichokes, simply thaw them in the refrigerator overnight if frozen, or remove them from the refrigerator if refrigerated. You can then steam, sauté, roast, or use them in any recipe that calls for artichokes, enjoying their fresh taste as if they were just picked.
With this step-by-step guide, preserving artichokes under vacuum has never been easier. Whether you plan to savor them for future recipes or want to savor their taste year-round, vacuum-sealing ensures your artichokes stay deliciously edible whenever you desire.
