Blue Potato Gratin from WeeliciousPin

I wanted to cook something festive and naturally colorful for the 4th of July and came up with this heavenly blue potato gratin. Not wanting it to have a heavy 
cream sauce, I thought that the idea of “cauliflower cream” sounded so 
much more nutritious and delicious. Its kind of surprising that the cream’s main ingredient 
is a vegetable since it has such an undeniably rich taste. Let it be known, though, I don’t 
want to deceive Kenya into thinking he’s getting cream sauce. I want him to know 
that even cauliflower can be the star ingredient of a dish and give you just as much flavor, if not more, than heavy cream.
This is one of those perfect dishes to serve on the fourth because the 
adults will dig it too. I made it for a party and everyone loved the 
red, white and blue theme. Kenya loved peeling apart the layers and 
eating them one by one. Although weelicious stands by the concept that every recipe should be easy, 
fast and fresh, this one might take you a few extra minutes. But for 
me, it was worth it!
