Key Lime Pie

Today is National Pi Day, that’s “Pi”, not “Pie”.  Pi is the symbol that shows the ratio of a circle’s circumference to its diameter, which is approximately 3.1415926… and so on!  Pi Day is always on March 14. But what is neat about today’s date “3/14/15” is that the digits are in order with the first 5 numbers of Pi.  Most years only the first 3 digits are associated with the date.   So we have the bonus of the 2015 for this year.  And an added bonus.. how about a recipe for Pie??  😉

I’m sharing a recipe for Key Lime Pie today.  It’s one of my favorites.  Has a little tang to it.  You can use key limes, if you can find them but regular limes work just fine.  You’ll be making a meringue topping for this pie.  It’s delicious!  I’ve tried several recipes for the pie, but this one is my favorite.  Personally, I prefer a graham cracker crust with this pie, but you can use a regular pastry crust if you prefer.  You can add a few drops of green food coloring to the filling of the pie if you would like to make your pie to look greener.  I don’t do that, still tastes great with its natural color.
