Lemons/Limes

Peak Season: Lemons, year-round; limes, May to October

Perfect Pick: Brightly colored, well-shaped with smooth, thin skin. They should feel sturdy but give every so slightly when squeezed. Small brown splotches on limes do no affect flavor (although they are a sign of deterioration and those with splotches should be consumed first).

Handle with Care: Store at room temperature, in a dark location, for about 1 week or refrigerate for up to 2 weeks.

The Payoff: Phytonutrient liminoids, which appear to have anticancer, antiviral properties.
