Start by poaching the chicken breasts in a pot with water, celery, onion, and peppercorns until they are cooked through.
Remove the chicken and let it cool.
Once cooled, shred the chicken into bite-sized pieces using forks or by hand for a more rustic texture.
This will be the base for your salad.
In a large mixing bowl, combine the shredded chicken with mayonnaise and fresh lemon juice.
Stir to coat the chicken evenly and ensure the flavors spread through.
Add red grapes, chopped celery, and sliced almonds to the chicken mixture.
Sprinkle curry powder, salt, and pepper over the top.
Mix everything until ingredients are well combined.
Refrigerate the chicken salad for at least an hour before serving to allow the flavors to meld together.
It tastes even better when chilled.
