TL;DR

• Select artichokes that are heavy for their size, have tightly packed leaves, and make a slight squeaking sound when gently squeezed.
• Store artichokes in the refrigerator at 32-40°F (0-4°C) with 90-95% relative humidity for optimal freshness.
• Properly stored fresh artichokes typically last 5 to 7 days in the fridge.
• Freeze-blanched artichokes for up to 6 months for longer storage.
• When preparing artichokes, trim the stem to make the bottom flat and snip off the thorny leaf tips.
• Retailers should keep artichokes refrigerated between 32-41°F (0-5°C) with high humidity (around 95%) to maintain freshness.

Introduction

Artichokes are a delicious and unique vegetable, but their short season and tricky preparation can intimidate even adventurous cooks. With the right know-how, you can confidently select the best artichokes at the store and keep them fresh for your favorite recipes. This guide will walk you through everything you need to know to become an artichoke aficionado.

Choosing the Best Artichokes

Your artichoke journey begins at the grocery store or farmer’s market. Keep these tips in mind to pick the cream of the crop:

• Look for artichokes that feel heavy for their size and have tightly packed leaves
• The leaves should be a vibrant green color, not brown or dried out
• Gently squeeze the artichoke – it should make a slight squeaking sound (7, 8)
• Avoid artichokes with split, pitted, or spongy leaves

Prepping Artichokes for Storage

Cleaning and Trimming

Once you’ve brought your artichokes home, give them a quick clean-up before storing them:

1. Rinse the artichokes under cool running water and pat dry
2. Use a sharp knife to slice off the stem so the bottom is flat (9)
3. With kitchen shears, snip about 1/2 inch off the thorny leaf tips (7)
4. For easier cooking later, you can also cut off the top inch of the artichoke

To Wash or Not to Wash

Some artichoke aficionados actually advise against washing artichokes before storing them, as the excess moisture can speed up spoilage. If you do rinse your ‘chokes, be sure to dry them very thoroughly. Alternatively, simply brush off any visible dirt or debris and call it a day.

Refrigerating Fresh Artichokes

Ideal Storage Conditions

Your refrigerator’s crisper drawer is the perfect home for artichokes. Aim to keep them between 32-40°F (0-4°C) with a relative humidity of 90-95% (1, 2). Store the artichokes unwashed in a plastic bag, away from ethylene-producing fruits like apples, pears, and bananas.

Maximizing Fridge Life

Want to help your artichokes stay fresh even longer? Before sealing them in the plastic bag, sprinkle the stem ends with a few drops of water to retain moisture. When properly stored, fresh artichokes will typically keep for 5 to 7 days in the fridge (3). Watch for signs of spoilage, like fuzzy mold or slimy leaves, and discard any past-their-prime specimens.

Freezing Artichokes for Longer Storage

Blanching for Best Results

If you find yourself with more artichokes than you can eat in a couple of weeks, consider freezing them for longer storage. Here’s how:

1. Blanch the artichokes in boiling water for 5-7 minutes until tender-crisp (5)
2. Immediately transfer to an ice bath to stop the cooking process
3. Drain the artichokes well and pack them into airtight containers or freezer bags
4. Freeze for up to 6 months (4)

Thawing and Using Frozen Artichokes

To use your frozen artichoke stash, either thaw them overnight in the fridge or cook them directly from frozen. For the best texture, use thawed artichokes within a day or two. Keep in mind that previously frozen artichokes will be a bit softer than fresh, so they work best in dishes like dips, soups, or pasta rather than steamed whole.

Other Preservation Methods

Marinating Artichokes in Oil

Marinated artichokes are a classic addition to salads, appetizers, and antipasto platters. To make your own, steam or boil the artichokes until tender, then submerge them in a flavorful bath of olive oil, vinegar, herbs, and spices. When refrigerated in an airtight container, they’ll keep for several weeks.

Pickling or Canning Artichokes

For the ultimate in long-term artichoke storage, you can pickle or can them. Prepare a pickling brine with vinegar, water, salt, and sugar, then pour it over cooked artichokes packed into sterilized jars. Process the jars in a boiling water bath for shelf-stable storage, or simply refrigerate for a quicker pickle.

Tips for Grocers and Retailers

Grocery stores and markets can ensure their artichokes stay fresh and fly off shelves with these practices:

• Carefully inspect shipments for any signs of damage or decay
• Keep artichokes consistently refrigerated between 32-41°F (0-5°C) with high humidity (around 95%) (6)
• Display artichokes stem-side down on refrigerated shelves or stands
• Avoid displaying artichokes in direct contact with ice to prevent water-logging
• Rotate stock regularly, removing any spoiled or past-prime specimens
• Create an attractive, appetizing display with artful arrangement and periodic misting

Conclusion

Artichokes may seem intimidating at first, but with a little know-how, you’ll be cooking and enjoying them like a pro. The key is starting with the best quality artichokes, storing them properly to maximize freshness, and getting creative with preparation methods. Don’t be afraid to experiment – artichokes are incredibly versatile and shine in everything from creamy dips to flavorful pasta dishes. With the right techniques, you can savor the delicate, one-of-a-kind flavor of artichokes whenever the mood strikes.
