Succulent pink shrimp and crisp, sweet water chestnuts are briefly simmered in a light cream-enriched stock. The dusting of spices highlights the natural flavors, rather than adds new tastes.
Shell and devein shrimp, placing shells in medium saucepan. Toss shrimps in bowl with salt and pepper, cardamom, and nutmeg; set aside.
Add stock to shells; boil 5 minutes. Strain; discard shells. Cut water chestnuts in fairly thick slices and add to stock. Simmer 5 minutes. Lift out with slotted spoon and set aside.
