Ina, Ina, Ina.  Your name may rhyme with a certain body part that shall not be named on this blog, but it doesn't make your recipes any less tasty.
Your cauliflower gratin was a delicious treat.  Creamy, cheesy, crispy on top.  
Maybe next time I would reduce the amount of milk you recommend in the recipe, to limit the soupiness.  Perhaps 1 1/2 cups rather than 2.  Also, I used panko bread crumbs, not fresh ones.  Because they're crunchy.  Don't hate me, Ina.
