Ingredients For Mashed Potato Salad Recipe
Potatoes: The base of the salad, providing a creamy and starchy texture.
Mayonnaise: Adds richness and a smooth, creamy consistency to the salad.

Mustard: Provides a slight tang and depth of flavor.
Salt: Enhances the overall taste of the dish.
Black pepper: Adds a hint of spice and warmth.

Technique Tip for This Recipe
When mashing the potatoes, ensure they are still warm to achieve a smoother texture. Cold potatoes can become gummy and difficult to mash properly. Use a potato masher or a ricer for the best results, avoiding a food processor which can overwork the potatoes and make them gluey.
