Mexican Lime (1 count)

Don't let the small size fool you — the Mexican lime packs more flavor per squeeze than the big, thick-skinned Persian limes that dominate grocery store shelves, and once you cook with one, it's hard to go back. Also known as the Key lime, this golf ball-sized citrus has a thin, fragrant rind and juice that's sharper, more floral, and more complex than its larger cousin — the kind of bright, insistent acidity that makes ceviche sing, lifts a taco to another level, and gives a margarita its backbone. The juice skews slightly bitter alongside its tartness, which is exactly what makes it so culinarily interesting — it adds dimension, not just sourness. And don't skip the zest: the oils in that thin skin carry a floral intensity the juice alone can't replicate.
