Store fresh artichokes in the refrigerator to slow down the degradation process. They are sensitive to warmth and can quickly spoil at room temperature.
When kept in the vegetable crisper drawer of the refrigerator, whole artichokes can last for about 1 to 2 weeks. Place them in a plastic bag to maintain humidity.
If you've already cut or trimmed the artichokes, they have a shorter shelf life. Use them within 1 to 2 days for the best quality.
Before purchase, choose artichokes with tight, compact leaves and vibrant green color. Avoid those with brown or dry spots, as they may indicate age or spoilage.
Trim the stem and any excess leaves before storing. Additionally, you can trim the top inch of the artichoke and sprinkle it with water to keep it hydrated.
For cut or cooked artichokes, store them in an airtight container in the refrigerator. This prevents exposure to air, reducing the risk of oxidation and spoilage.
If you cut artichokes, soaking them in water with a squeeze of lemon can help prevent browning. Lemon has antioxidant properties that slow down the oxidation process.
While freezing alters their texture, you can freeze cooked artichokes for future use. Blanche them first, then place in airtight containers or freezer bags. They can last for up to 6 months in the freezer.
