Some Spritz cookie recipes call for powdered sugar vs granulated sugar, and some recipes use egg yolk only vs whole egg. Without trying every recipe, what differences might result from these differences?
1 Answer
Powdered sugar would produce a smoother textured dough than granulated sugar, I think, as it would more easily be incorporated with the other ingredients than the larger grained, sandy texture created by granulated sugar.
Egg yolk only would have a higher fat content than whole egg, and the lack of egg white might produce more rich taste, but likely more tender cookies than those with the egg white, as protein in the egg white would hold crumbs together better.

1Additionally, you'll generally beat in more air creaming butter with granulated than with powdered.– jscsCommented Dec 29, 2017 at 20:59
