These cookies are a dream: intensely chewy, with gorgeous glossy tops and perfectly caramelized edges, all balanced with a sprinkle of flaky sea salt.
Ensure butter is only slightly cooled, not hot, to prevent cooking the egg.
Do not overmix the flour; stop as soon as it’s incorporated to keep cookies tender.
Chilling the dough for the full 30 minutes is crucial for cookie thickness and chew.
Tap the hot baking sheet immediately after baking to create glossy, crinkled tops.
