Fresh basil has a pungent flavor that some describe as a cross between licorice and cloves. It's plentiful during summer months, and available year-round in many markets. Choose evenly colored leaves with no sign of wilting. Refrigerate basil, wrapped in barely damp paper towels and then in a plastic bag, for up to 4 days. Or store a bunch of basil, stems down, in a glass of water with a plastic bag over the leaves.

Dried basil, though it bears little resemblance in either flavor or aroma to the fresh herb, can be purchased in the spice section of most supermarkets. Store dried basil airtight in a cool, dark place for up to 6 months.
