tablespoons whole milk (½ tablespoon for each egg)
teaspoons potato starch or cornstarch (½ + ⅛ teaspoon for each egg)
Salt to season
tablespoons unsalted butter (1 tablespoon for each egg)
First, crack 3 eggs into a medium bowl. Then, in a separate cup or bowl, evenly whisk together the milk and cornstarch until it's lump-free (don’t mix them directly with the eggs or you’ll get lumps). Add the milk and cornstarch mixture to your eggs, and beat until smooth. Season with salt. Heat a non-stick skillet over high heat until hot, then add the butter (should sizzle right away). Wait until the butter’s melted and bubbly, but before it browns… Add the beaten eggs. Wait for 3 seconds without stirring anything, until the edges of the eggs start to bubble up… Then remove the skillet from the heat (yes, remove!), and start stirring the eggs, making 1 full circle per second… 1, 2, 3…. 4, 5, 6, 7…8, 9, 10, 11…(If you use a mini skillet instead of a large one, it may need a few more seconds)... For about 11 to 12 seconds. The eggs will have absorbed all the butter, but remain partially undercooked (add about 5 seconds more to every 3 extra eggs you’re scrambling, but I wouldn’t do more than 6 at once). This is when you transfer them onto a plate. Do not wait until they look fully cooked!
