2 tablespoons unsalted butter β melted and cooled
1 tablespoon unsalted butter β for the pan
Instructions
Melt 2 tablespoons unsalted butter over low heat until just liquid, 1β2 minutes; set aside to cool 5 minutes.
In a medium bowl, whisk together the flour, sugar, and salt until evenly combined, 15β20 seconds.
In a separate bowl or large measuring cup, whisk the eggs with about half the milk until smooth, 30β45 seconds.
Gradually whisk the eggβmilk mixture into the dry ingredients until no dry pockets remain, then whisk in the remaining milk until the batter is silky and mostly lump-free, 1β2 minutes. Whisk in the melted butter until fully incorporated, 15β20 seconds. Strain the batter through a fine-mesh sieve if any lumps remain, 30 seconds.
Cover and rest the batter to hydrate, 30β60 minutes at room temperature (or up to 24 hours refrigerated). If chilled, let stand at room temperature 15 minutes before cooking.
Check consistency: the batter should flow like heavy cream. If too thick, whisk in 1β3 tablespoons additional milk until it thinly coats the back of a spoon, 30 seconds.
Heat a 9β10 inch nonstick skillet or crepe pan over medium heat until evenly hot, 2β3 minutes. Lightly brush with a small amount of the 1 tablespoon butter for the pan until just glossy, 5β10 seconds.
Pour in about 0.25 cup batter, immediately tilting and swirling to coat the pan in a thin, even layer. Cook until the edges look dry and the underside is pale golden with light browned spots, 45β60 seconds. Flip with a thin spatula and cook the second side until just set, 20β30 seconds. Transfer to a plate.
Repeat with remaining batter, lightly brushing the pan with more butter every 2β3 crepes and adjusting heat to maintain gentle browning, 10β15 minutes total. Stack crepes and keep warm under a clean towel; fill or serve as desired while warm.
