Globe artichokes are available year-round.
When selecting Globe artichokes, look for compact and heavy buds with deep green bracts that squeak when squeezed. Smaller artichoke hearts will be more tender than larger ones. Avoid artichokes with wilted or discolored leaves and shriveled appearance as these are signs of age. Artichokes should keep well for up to two days in the refrigerator.
Store artichokes immediately in the crisper drawer of the refrigerator for up to two days. Do not wash until ready to use or steam. The choke will darken with exposure to air, so as soon as it is removed, the artichoke should be immersed in cold water with a little lemon juice to prevent discoloration. Steam or cook artichokes as soon as possible after trimming to ensure flavor and texture are at their best. Any cooked leftovers should be refrigerated in an airtight container for up to three days.
Globe artichokes are a nutrient-dense food, with high levels of dietary fiber, vitamins, minerals, and antioxidants. They are a good source of vitamin C, folate, magnesium, potassium, iron, manganese, phosphorus and zinc. Artichokes also contain phytonutrients such as phenolic acids and flavonoids which have anti-inflammatory, antioxidant and cholesterol-lowering effects.
Globe artichokes should be washed and trimmed to remove the outer leaves and stem before cooking. The choke can then be steamed, boiled, or microwaved. To steam, place in a steamer basket over boiling water for 15-20 minutes until tender when pierced with a knife. Boiled artichokes should be submerged in boiling salted water for 20-30 minutes. When microwaving, place the artichoke in a bowl with 1/4 cup of water and cook for 8-10 minutes. Once cooked, the heart can be removed easily from the center and eaten directly or used in salads, pasta dishes, dips, or other recipes.
