Follow these steps to bring your Deviled Egg Bar to life:

1. Place the eggs in a single layer in a saucepan and cover them with water. Bring the water to a boil over high heat. Once boiling, cover the pan, turn off the heat, and let the eggs sit for 12 minutes.
2. Transfer the eggs to an ice bath to cool for at least 5 minutes. This step ensures easy peeling.
3. Once cooled, peel the eggs and slice them in half lengthwise. Gently remove the yolks and place them in a mixing bowl.
4. Mash the yolks with a fork and mix in mayonnaise, Dijon mustard, vinegar, salt, and pepper until smooth and creamy. Adjust seasoning to taste.
5. Spoon or pipe the yolk mixture back into the egg whites, dividing it evenly among the halves.
6. Arrange the filled eggs on a platter and set out a variety of toppings in small bowls. Encourage guests to garnish their eggs as they desire.
7. Enjoy the creativity and conversation that naturally flows as everyone designs their perfect deviled egg.
