Expert tips:

  • Make sure you press the honey graham cracker crumbs as firmly as possible into the pie plate. If you don’t press them in firmly, it will crumble and fall apart when you slice and serve.
  • Choose limes and/or key limes that give a little when you squeeze them to make sure they are juicy.
  • Only grate the green part of the lime. Don’t grate all the way down to the pith (the white part) which can be bitter.
  • Key lime pie is best served chilled (more refreshing and tastier).

FAQ:

  • Can you make this recipe in advance? Yes, you can make it from 6 hours to 2 days in advance.
  • Does key lime pie need to be refrigerated? Yes because of all the dairy in it.
  • Where did key lime pie originate? I always thought this pie was invented in Key West, Florida, hence the name. However, there is a debate about this. Some say it was actually invented by the Borden milk company in New York City to sell more sweetened condensed milk. This mystery dates back to the 1930s, so no one knows for sure.
