Spargelsuppe with Morels

Spargelsuppe: That’s German for “white asparagus soup.” This one is super elegant and doesn’t call for cream. White asparagus are, to quote Cook’s Illustrated, “simply green asparagus that have never seen the light of day.” Soil is mounded over the asparagus as it grows, blocking the sun. As a result, the plant’s chlorophyll and its associated greenness never develop. White asparagus stalks should be peeled, as their skin is bitter, but underneath, they are sweet and tender. T
