WHY THIS RECIPE WORKS Cream of asparagus soup should be bright green, bursting with asparagus flavor, and flawlessly smooth, but often the butter and cream stirred in before serving make the soup heavy. To eke out maximum asparagus flavor, we tried sautéing the spears, but ended up with a dark, bitter soup. Broiling the asparagus yielded similar results. Lowering the heat and cooking the asparagus spears gently to slowly coax out their flavor worked. (Tasters agreed that the richness of butter was a must here.) We learned the hard way not to overcook the asparagus; to retain their fresh flavor, the pieces must be just tender enough to puree. To achieve more creaminess without adding more cream, leeks, which are great for adding sweet silkiness without muddling flavors, came to mind. For a beautiful emerald hue, we stirred a handful of peas into the pot just before pureeing. They added further sweetness and body, thanks to their starch. A bit of Parmesan lent a nuttiness that echoed that of the asparagus, while lemon juice brightened the dish. Look for asparagus spears no thicker than ½ inch.
