MRS. MORILL'S DEVILED EGGS

Boil one dozen eggs hard, remove the shells and cut in halves lengthwise.  Take out the yolks, mix them to smoth paste with a half a teaspoonful of mustard, salt and cayenne pepper to taste and a generous teaspoonful of Worcestershire sauce.  Fill the whites with this mixture and serve on a bed of lettuce leaves, which should be carefully selected.
