Kale

Look: Firm, deeply colored leaves with crisp edges — skip bunches with yellowing or ragged holes.
Feel: Leaves feel thick and springy and the stems snap instead of bending.
Smell: Mild and cabbage-sweet; a strong sulfur whiff means it has sat too long.
Tip: Shop after the first hard frost — cold snaps turn kale noticeably sweeter.
Keeps: Fridge in a bag, up to a week.
