How to add pause between each iteration of jQuery .each()?

I added this as a comment but now that I have read it correctly and answered my own question this would probably work:

function positionCards() {
  var $cards = $('#gameboard .card');

  var time = 500;

  $cards.each(function() {
      setTimeout( function(){ addPositioningClass($(this)); }, time)
      time += 500;
  });
}
