Expert Tips

  • Tip 1
    Key limes, grown in Florida, are smaller and rounder than the common, more familiar green--or Persian--limes, and their colour is more yellow than green. Although Key limes are less widely available than the common lime, bottled Key lime juice is generally available.
  • Tip 2
    If you like your Key lime pie to have a green colour instead of the characteristic yellow, beat in a few drops green food colour with the condensed milk.
