Key limes appear smaller than their counterparts do, but their juice packs a more intensely flavorful punch. Because of this, you will need to use a third less of the amount of key lime juice in recipes. Although squeezing limes can become a messy task, it will be well worth the effort. Liven up recipes with fresh key lime juice.
Wash the limes with cool water. Dry them off with a paper towel.
Clean an area on your kitchen counter. Allow the limes to sit at room temperature. Roll them on the counter with the flat part of your hand while simultaneously pressing down on the lime.
Cut ¼ to ½ inch off the bottom of the lime. This will allow you to stand it up straight to cut it with some stability.
Slice a side off the lime. Make the slice off-center to break the membranes to squeeze the juice out easier.
Make two additional off-center cuts. This should leave you with three pieces of lime.
Twist the core off. You will be able to squeeze juice out of this too.
Hold the lime pieces over a container by the rind. Point the lime fruit toward the container, and squeeze to release the juice.
