Wendys Tips

Cut evenly: Cutting your potatoes into uniform pieces ensures they cook at the same rate.
Don’t overmix: Overmixing mashed potatoes can make them gummy. Mash just until smooth.
Warm your milk: Adding cold milk can cool down your potatoes and make them lumpy. Warm it up first for the best results.
Taste as you go: Add salt and pepper little by little, tasting each time.
