A lime’s internal structure is different than a lemon, so the cutting it in-half method may actually not produce maximum juice.

To get the most juice you can out of your lime, cut your lime lengthwise, rather than crosswise, just to the side of the stem. You will end up with four side pieces and a core. Juice the four side pieces by squeezing with your fingers. Juice the core piece by twisting it as if wringing water out of wet clothing.
