To ensure food safety, eggs should be cooked until both the yolk and the white are firm. Consuming raw or undercooked eggs may increase your risk of foodborne illness, especially for those with certain medical conditions. For recipes that call for eggs that are raw or undercooked when the dish is served, use either pasteurized shell eggs that have been treated to destroy Salmonella, or use pasteurized egg products.
Deviled eggs can be made up to 12 hours ahead. Refrigerate, covered.
Very fresh eggs can be difficult to peel. To ensure easily peeled eggs, buy and refrigerate them a week to 10 days in advance of cooking. This brief “breather” allows the eggs time to take in air, which helps separate the membranes from the shell.
Hard-boiled eggs are easiest to peel right after cooling. Cooling causes the egg to contract slightly in the shell.
To peel a hard-boiled egg: Gently tap egg on countertop until shell is finely crackled all over. Roll egg between hands to loosen shell. Starting peeling at large end, holding egg under cold running water to help ease the shell off.
Hard-boiled egg storage time: In the shell, hard-boiled eggs can be refrigerated safely up to one week. Refrigerate in their original carton to prevent odor absorption. Once peeled, eggs should be eaten that day.
No-mess method: Combine filling ingredients in 1-quart plastic food-storage bag. Press out air and seal bag. Press and roll bag with hand until mixture is well blended. Push filling toward bottom corner of bag. Snip off about 1/2-inch of corner. Squeeze filling from bag into egg whites.
Picnic or tailgate tip: Prepare filling in plastic bag, as above. Carry whites and yolk mixture separately in cooler. Fill eggs on the spot, pressing filling out of snipped corner of bag.
