When the Roman emperor Augustus Caesar wanted a quick end to a distasteful task, he’d proclaim: “Velocius quam asparagi conquantur.”

“Let it be done quicker than you would cook asparagus.”

That was, of course, long before the invention of the microwave. These days there’s nothing drawn out about steaming the nutritious spring stalks. Luckily the quick-cooking method also naturally preserves precious nutrients.

Since ancient times the luscious grass-green spears have been considered good for what ails you: a remedy for heart trouble and toothaches, an antidote for bee stings, a reproductive tonic and a natural diuretic.

Asparagus has fewer than 5 calories per stalk and is high in folic acid, which may prevent birth defects. The National Cancer Institute has named asparagus the food highest in glutathione, an antioxidant and potent cancer fighter; it also a good source of vitamin A, B6 and C, calcium, iron, thiamin, potassium and fiber.

Too often served drenched in butter or hollandaise sauce, mild, earthy asparagus is just as suited to lighter preparations. The Star’s Asian Marinated Asparagus bathes the spears in a mixture of low-sodium soy sauce, rice wine vinegar, ginger and lemon. The dish is served cold, and etiquette experts say it’s OK to eat the slender stalks with your fingers.

Shopping tip:

Most of the phytonutrients are in the tips, so choose asparagus with tightly closed tips. Look for sesame oil in the ethnic foods aisle.

• 

Preparation tip:

Asparagus grows in sandy soil, so wash tips well to remove any grit.

The natural sugars in asparagus quickly turn to starch. To remove the tough, woody ends, simply hold each stalk, one at a time, between your hands and bend where it naturally breaks.
