This bright yellow/green citrus fruit is oval in shape, with a pronounced bulge on the blossom end. The flesh is juicy and acidic. They can range in size from that of a large egg to that of a small grapefruit. Some have thin skins while others have very thick rinds, which are used to make candied lemon peel. Lemons/limes are available year-round with a peak during the summer months. Should be firm, plump and heavy for their size. Depending on their condition when purchased, they can be refrigerated in a plastic bag for 2 to 3 weeks.
