*Use “regular” (Persian) limes if Key limes not available
What are Key limes?
Key limes (aka Mexican limes) are more tart than “regular” limes, and get their name from having originally been grown commercially in the Florida Keys. After being wiped out in the 1920’s from a hurricane, most limes now grown in the Keys are the Persian variety, what we typically see in the grocery store.
Key limes are smaller than Persian limes, so they will take a bit more work (and quantity) if you find them, but worth it for some recipes (like pie). Their flavor is somewhat unique, although you can usually sub one juice equally for the other. Some suggest 3/4 Persian lime plus 1/4 lemon to mimic Key lime flavor. Just refrain from using the bottled juice as a sub. Either variety of fresh lime will work fine in our ice cream sandwich recipe!
