Cultured buttermilk does more than tenderize—the slight tang streamlines batter consistency, letting you skip any leavening aids and still get ultra-thin, lacy crêpes. It’s also a practical way to rescue that lingering carton of lait ribot, transforming a fridge staple into a versatile canvas for rapid weekday fillings or brunch spreads.
All-purpose flour (250 g)
Measure the flour into a large bowl
Chef’s Note: After whisking, pour the batter through a fine-mesh sieve and let it rest; straining knocks out hidden lumps so the crêpes spread in a whisper-thin sheet. For a savory twist, swap one-third of the wheat flour for buckwheat and skip the sugar—the buttermilk keeps them just as supple.
