I have ALWAYS used a recipe called “Never Fail Pie Crust” (with vinegar and egg - you know the one!)  my entire life - and never thought I would find one I like better.  I must say this one comes close!  It is very easy, and the butter gives it an even better flavor for some pie fillings I use.  I’m not sure why it works so well, but I love it for main dish pies - like pot pies and quiche.  Equally good in standard fruit and cream pies also.
