My son, who is a trained professional chef, grilled potatoes for me last week. I liked what he did. I tried the technique myself only a hotter temp. I cleaned my potato, gave it an olive oil coating plus kosher salt and cracked pepper. I baked it on the grill with lotsa oak smoke at 500 degrees for 45 minutes. It was just awsume. Loved the flavor of the smoke and the dried potato skins with just butter, salt and pepper.
