Best Chicken Salad - Ever! - cooking recipe

Ingredients

6 cups shredded cooked chicken, from rotisserie chicken
1 cup mayonnaise, homemade, recipe below
2 stalks celery, finely diced
1/4 cup scallion, chopped
1/2 cup chopped fresh herb, parsley, basil, and thyme work well
1 lemon, zested
1 -2 tablespoon fresh lemon juice
1 egg yolk
1/2 teaspoon salt
1/2 teaspoon dry mustard (or dijon mustard)
1 pinch sugar
2 tablespoons fresh lemon juice
1 cup canola oil

Preparation

For homemade mayonaise - in a glass bowl, whisk together the egg yolk and other ingredients (except the oil). Starting very slowly (just a drop at a time) whisk the oil into the egg yolk mixture. Once an emulsion forms you can increase the oil to a thin stream. Continue whisking in the oil until it is all incorporated. Can be refrigerated up to one week.
Combine chicken with enough mayonnaise to moisten (according to taste). Fold in the celery, scallions and herbs. Season with salt and lots of pepper.
