I'm a novice cook, but was intrigued by Megan McArdle's simple-enough-even-for-me recipe for frozen artichoke hearts:
I'm also an enormous fan of frozen artichoke hearts, which when roasted at 500 degrees with a little spritz of olive oil and a sprinkling of sea salt, make a delicious, inexpensive, low calorie and high fiber dinner or side dish. We always have them in our freezer, and after eating same at our house, some friends have started stocking up as well. Are they quite as good as fresh grown, local artichokes would be? No. But local artichokes aren't available for very long in Washington, DC, and I tend to get discouraged by the task of cutting down twelve artichokes to extract the heart.
OK, I have all the ingredients, but a question remains: how long should I bake the hearts at 500°?
