Curry and Crab Deviled Eggs:

Greek-Style Deviled Eggs:

Prepare as above, except fold 2 Tbsp. crumbled feta cheese, 1 Tbsp. finely chopped pitted kalamata olives or other pitted ripe olives, and 2 tsp. snipped fresh oregano into yolk mixture. If desired, season with black pepper.

Chipotle Deviled Eggs:

Prepare as above, except omit mayonnaise, mustard and vinegar. Stir 1/4 cup dairy sour cream, 1 tablespoon finely chopped green onion, and 1 teaspoon finely chopped canned chipotle peppers in adobo sauce into yolk mixture.

To Hard Cook Eggs:

To hard-cook the eggs, place 6 large eggs in a single layer in a large saucepan (do not stack eggs). Add enough cold water to cover the eggs by 1 inch. Bring to a rapid boil over high heat (water will have large rapidly breaking bubbles). Remove from heat; cover and let stand 15 minutes. Drain. Run cold water over the eggs or place them in ice water until cool enough to handle; drain. To peel eggs, gently tap each egg on the countertop. Roll the egg between the palms of your hands. Peel off the eggshell, starting at the large end.
