If desired, remove skin from the middle of each potato. Place potatoes in a large pot and cover with 1 inch of water. Add 1 teaspoon salt and bring to a boil. Simmer 20 to 25 minutes or until soft.: The skins on small potatoes are thin and often add pleasant texture, but if you prefer a more uniform mouthfeel remove a strip of skin from the middle. You may notice a faint earthy scent as you peel, and the exposed flesh will look pale and slightly moist. A common mistake is over peeling which wastes flavor and nutrients, so remove only what you need if texture is your concern.
Drain potatoes well and return to pot.: When you add enough water to rise about one inch above the potatoes , they cook evenly from the outside in. As the pot warms, tiny bubbles will form on the sides before a full simmer, and the water may look slightly cloudy as starches release. An error here is crowding the pot which can lead to uneven cooking, so use a pot that gives the tubers space to move.
Add butter, garlic powder, and parsley. Toss to coat well.: Adding salt to the cooking water seasons the potatoes from the inside out, improving their flavor in a way that salting after cooking cannot fully replicate. You will hear the water shift from quiet simmering to a rolling boil with louder bubbling and a stronger steam aroma. Avoid boiling too vigorously which can cause the skins to split and over soften the interiors.
Add salt and pepper to taste.: As the potatoes simmer, the scent of cooked starch becomes warm and slightly sweet, and a fork will slide through the flesh with gentle resistance when they are done. Test by piercing the largest potato in the pot, the center should be tender with no hard core. A common oversight is to undercook which yields chalky centers, so test several pieces to ensure uniform doneness.
Drain potatoes well and return to pot: Draining removes excess water that would dilute the finish, and returning them to the still warm pot lets residual heat evaporate lingering moisture. You may hear a light rattling as the potatoes settle in the colander, and the pot will release a faint, comforting steam when they go back in. Avoid leaving them in a wet pot which can make the final coating of butter slide off rather than adhere.
Add butter, garlic powder, and parsley: When you add the slivered butter , it will melt almost instantly against the hot surfaces, releasing a nutty aroma and creating a glossy coating. The powdered garlic blends into the butter and warms up, while the chopped parsley will begin releasing its herbaceous scent. Stir so the flavors mingle and coat each piece; a frequent mistake is adding cold ingredients that chill the potatoes , so ensure your additions are at room temperature for smooth integration.
Toss to coat well: Tossing distributes the melted butter and seasonings, producing an even sheen and balanced taste. As you toss, listen for a quiet clinking and watch for a uniform glossy look across the potatoes . If you see pools of butter settling at the bottom, continue to toss gently until it is absorbed, and do not overwork them which can break the pieces apart.
Add salt and pepper to taste: Finishing with salt and pepper allows you to tailor the final seasoning. Taste a warm bite to judge how much more is needed, and keep in mind the melting butter can mute flavors slightly so adjust accordingly. A typical error is over salting early in the process; it is safer to start with less and add more as you taste.
