Boil eggs: Gently place eggs in a single layer in a medium pot and cover with cold water by 1 inch. Bring water to a boil over medium-high heat, and once it comes to a strong boil, set a timer for five minutes. After five minutes, remove eggs from heat, discard hot water, and run eggs under cold water until cool. Once cool, drain water and refrigerate until you’re ready to use. Once the hard-boiled eggs have cooled, carefully peel them and slice them in half lengthwise. Remove the yolks and place them in a separate bowl.
Mash and mix: Mash the egg yolks with a fork or masher until they are crumbly. Add the mayonnaise, vinegar, and salt to the bowl with the egg yolks. Mix well until all the ingredients are thoroughly combined and the mixture is smooth.
Taste and adjust: Taste the filling and adjust the seasonings according to your preferences, adding more salt, vinegar, or mayonnaise if needed.
Fill egg halves: Spoon or pipe the yolk mixture back into the egg white halves, dividing it evenly among them.
Chill and serve: chill the jalapeño deviled eggs in the refrigerator for at least 30 minutes before serving.
To serve: When serving, consider adding a small slice or dice of pickled carrots and jalapeños on top of each deviled egg for visual appeal and an extra burst of heat.
