- Trim raw artichokes as desired. At a minimum, peel off all the outer, hard, spiky leaves. I prefer peeling off all the leaves and all the fuzz. Keep the stems, but peel them. This method is time-consuming.
- Precook the artichokes (boil for 45 minutes or so, until the inside is tender: poke with a skewer to check). Let them cool down; then trim them. (BTW, the tender parts of the leaves are good to eat.)
- Start with a can or two of artichoke hearts; drain. Canned artichokes come packed with water containing citric acid, which is likely to be a corn product. Most of this should be removed by the next step, but be aware that this method may not be 100% corn-free.
- Raw, thoroughly trimmed artichokes: 20 minutes or so, until tender.
- Precooked artichokes: 3-5 minutes, until hot throughout.
- Canned artichokes: 3 minutes.
