Good-quality nectarines will be fairly large, have smooth, unblemished skin and will be firm but not rock-hard. Ripen nectarines at home for 2 to 3 days at room temperature until they are slightly soft along the seam. Ripe fruit will have a sweet nectarine smell that is stronger when the fruit is at room temperature.
Avoid product that is too small, too soft, pitted, bruised or has small spots of mold.
