What makes a good egg salad sandwich? Everyone has their own answer to this question. For me, it all starts with fresh, perfectly cooked soft-boiled eggs. I add a little crunch for texture, a little acidity to balance out the creaminess of the eggs, and a dollop or two of mayonnaise to bind it all together. I add some tarragon, curry powder, and dry mustard to make my perfect egg salad. I love the taste of tarragon and it goes perfectly with eggs. It's really very simple and easy to make.
Prepare an ice bath by filling a bowl with ice water and set aside.
Place the eggs in a pot, fill with water to cover eggs by about 1/2-inch, and bring to a gentle boil. Turn off the heat, cover, and let sit for 7 – 10 minutes, depending on your preference for doneness. (I let mine sit for 7 minutes since I prefer softer-boiled egg yolks.) Remove and transfer to the ice bath for about 5 minutes to stop the cooking.
Peel eggs and place in a mixing bowl. Add the mayonnaise, lemon juice or white wine vinegar, and season with salt and pepper. Mash with a fork.Add in the celery, curry powder, dry mustard, and tarragon. Taste and adjust the seasoning, if needed.
To assemble the sandwich, place a handful of lettuce and a scoop of egg salad between two pieces of bread.
