What method is BEST suited to separate a mixture of two miscible liquids with different boiling points (e.g. water and ethanol)?

Distillation works by heating the mixture — the more volatile liquid (lower boiling point) vaporises first, is condensed and collected, separating it from the less volatile one. Filtration is for solid-liquid mixtures; evaporation only recovers the solid; sedimentation lets heavier solids settle.
