This technique makes starchy Russet potatoes act like creamy Yukon Golds, and also makes some of the crispiest edges we've ever tasted. It's a little like Jeffrey Steingarten's famous single-layer potato gratin, pared down to three ingredients. Recipe adapted very slightly from Seven Fires: Grilling the Argentine Way (Workman Publishing, 2009).
Ingredients
For the clarified butter

Directions
Instructions
- Step 1
For the clarified butter:
- Step 2
Slowly melt butter in a small heavy saucepan over medium-low heat; do not stir.
- Step 3
Remove from the heat, and carefully spoon off any foam from the top.
- Step 4
Pour the clear liquid butter through a fine-mesh strainer, leaving behind the solids in the pan.
- Step 5
Once cool, the clarified butter can be refrigerated for weeks.
- Step 6
For the potato dominoes:
- Step 7
Heat a home oven (with the rack positioned in the center of the oven) to 400°F. Line a rimmed baking sheet with a Silpat or use a nonstick baking sheet.
- Step 8
Cut off the two ends of one potato and reserve them. Trim the 4 sides of the potato to form an even brick. Slice the potato about 1/8 inch thick on a mandoline, keeping the slices in order if you can (just like a line of shingled dominoes).
- Step 9
Hold the stack of potato slices in the palm of one hand and use the other to shape them back into a brick -- as you would a deck of cards. Lay the stack on its side on the baking sheet, and put the reserved potato ends, cut side down, at either end to keep the stack aligned.
- Step 10
Then, with the palm of your hand, angle the slices slightly to resemble a line of dominoes that has tilted over. Adjust the end pieces to keep the stack in shape, and align the slices if necessary. Dot the top and sides with 1 tablespoon of the clarified butter.
- Step 11
Sprinkle with salt to taste. Repeat with the remaining potatoes, keeping the stacks at least 2 inches apart.
- Step 12
Bake for 40 minutes, or until the potatoes are browned on the edges and tender in the middle when tested with a skewer. Serve immediately.
