It’s no surprise to see an abundance of flourless chocolate cakes and incredible matzo bark covered in chocolate and butter during Passover — leavened products are forbidden during the holiday, so decadent substitutions are available. In the most-recent issue of Food Network Magazine, the Test Kitchens prepared five cakes without using all-purpose flour (pictured above is Flourless Red Velvet Cake, get more recipes below) to try at home and the results were tremendous. That led us to picking baker and co-owner of Breads Bakery in New York City Uri Scheft’s brain, to dive a little deeper into the subject. The world of starches, flours and desserts is so vast and can be overwhelming — so we turned to an expert.
What would kosher potato starch do to a cake? What type of cakes would you use this substitution in?
Uri Scheft: Potato starch sucks all of the liquid out, but because of the lack of gluten, it doesn’t really bind the ingredients. It leads to a more crumby, more dense cake that hasn’t risen as much. It is good for brownies because they don’t need to rise a lot. Additionally, they are better when not cooked completely through.
