As we continue exploring the "taste of America" in this column, we hear more and more that the public is patronizing restaurants which special- ize in what some food critics call "Mom" food. What is "Mom" food? It's basic neighborhood restaurant food such as meat loaf, pot roast, fried chicken, mashed potatoes, and candied carrots. Once again, we seem to be favoring the old standbys such as cheeseburgers, french fries and apple pie. The restaurant industry, through its various trade journals, report that in 1986 Americans ate enormous quantities of appetizers such as nachos, soups such as cream of brocolli, and tossed green salads. Prime rib was the top beef entree chosen in this country's restaurants, and the most favored poultry was roast turkey - a surprise for most of us who had believed that fried chicken was a strong leader. As no surprise was the report that french fries still command the number one spot for the favorite vegetable. And speaking of which - vegetables, that is - let's look at one superb vegetable that is a passion with the French: asparagus. A key factor in the enjoyment of this delightfully subtle vegetable is its tenderness after cooking. Be sure to keep your asparagus refrigerated at 34 to 36 degrees and to use it within 48 hours after purchase. When buying asparagus, consider thick stalks over thin ones. Firmness of the stalk is a definite quality factor. Break a stalk and notice that it breaks with a brisk snap. The top of the stalk, called the bud, should be compact and tight against the top of the stalk. If the bud is beginning to grey, be aware that the stalk has passed its prime and that this is a sign of over-maturity, which usually results in tough and stringy cooked asparagus. Keep in mind that only the green portion of this vegetable is edible. The white area near the butt of the stalk should be trimmed. The recom- mended method for cooking is steaming. A simple dressing of olive oil and fresh lemon juice brings out the taste of this seasonal vegetable. For the more adventurous, hollandaise sauce is the perfect accompaniment for creating a restrained elegance. Should the availability of fresh asparagus be a problem, then consider the frozen product. Avoid the canned product because my experience has been that it has two serious shortcomings: a tin can taste and over-tenderness. Most canned products tend to be over- blanched (partially cooked), which causes them to fall apart when served. The recipe for this column will deal with the simple preparation of Seasoned Fresh Asparagus. RECIPE NO. 7 - Seasoned Fresh Asparagus with Olive-Oil and Fresh Lemon Juice Yield: 8 four-ounce portions (To obtain 8 4-oz. portions, purchase between 3 1/2 to 4 pounds of asparagus. There will be as much as 40% waste.) Ingredients: 3 1/2 to 4 lbs. of fresh asparagus 2 ounces of olive oil The juice from 2 fresh lemons 1/2 teaspoon of salt Procedure: 1. Break or cut off tough stems (the white part). 2. Wash and thoroughly clean remaining portions - running water is preferred. 3. Arrange spears in one direction. 4. In a 2-quart pan place 1 1/2 quarts of water and salt. 5. Bring mixture to boil and add the asparagus as specified in No. 3 above. 6. Cover the pan and bring water quickly back to the boiling point. As soon as boiling begins, remove the cover. This will help retain the original color of asparagus. The process should take 15 to 20 minutes. 7. Take the asparagus pan away from the burner and drain the water. Throw ice cubes on the drained asparagus to retain the color. Allow it to stand for 3 to 5 minutes. 8. Place in a serving dish and pour the olive oil over the vegetable. 9. Cut the two lemons in four wedges each and place the wedges on the side of the asparagus. This will allow each guest to extract as much or as little lemon juice as desired. (C. "Gus" Katsigris is the Director of the Food and Hospitality Service Institute at El Centro College.
