When I began this food blog, encouraged by my sister Martha, who has two very fine blogs- crossing stitches and potpourri, I knew that whatever I made, my husband and I would have to eat as there are only two of us now.Cauliflower has never been a favorite food , as a matter of fact, white food in general-blanquette de veau comes to mind, is not a favorite. Vanilla ice cream and white desserts are exceptions. When Lara of Still Life With… whose photos are top notch and is admin of SLW-a group on Flickr chose white food as the January assignment, I had to re-think white food.While strolling around the produce section of my local grocery store, I espied a beautiful cauliflower and before I knew it, this gorgeous white vegetable was in my cart and I was headed home to cook -WHITE FOOD!! Actually, this is one of the tastiest cauliflower dishes I have eaten! It’s such a simple dish to prepare and the sauteed cauliflower slices give a little color and texture to the puree.Cauliflower Puree1 head of cauliflower, florets trimmed and roughly chopped.
