– Three Layer Parsnip Cake Recipe with Cream Cheese Frosting and Roots –
The longer I’ve been cooking, the more particular I become about the cookbooks I add to my collection. Far gone is my need for general cookbooks that teach classic techniques; instead, I’m looking for books that take a deep dive into a niche topic. At this stage in the game I’m hungry for nuance, the tiny details that general cookbooks almost necessarily glance over in an attempt to make the broad swath of information they impart less overwhelming. And indeed, the generalized cookbook has been done to death, with a few notable exceptions that are still useful to an old hand like me. I’ve entered my own personal era of the single-subject.
I have many criteria for the single subject cookbooks in my collection. First and foremost, the author must be inspired by the topic at hand, and that inspiration should infuse every page and every recipe they create. Second only to inspiration, these books must be compelling, urging even the most fatigued cook to jump to their feed and COOK. RIGHT. NOW. Finally, and perhaps this should be a given for any cookbook, there needs to be an educational component that teaches the reader something that he or she can carry with them in their most versatile cooking toolbox, their mind. If a book doesn’t teach me new things – ideally many – I consider it a wash.
Perhaps one of the most beautifully produced single subject I’ve received to date is Roots: The Definitive Compendium with more than 225 Recipes by Diane Morgan. The first thing a reader will notice when they pick up Roots is its matter-of-fact design. Much like the season during which we most enjoy root vegetables, this book’s stark, stoic aesthetic harkens to a cold Minnesota morning in January. It makes me think of my great grandmother riffling through the root cellar on her sugar beet farm, bundled up in many layers with her lips pursed in annoyance with the cold. The photos verge of gothic, celebrating the deep, saturated colors that are the signature of winter’s pause of sunlight.
The subtitle’s use of the term “definitive compendium” is not an exaggeration — in my opinion, this is for certain the foremost book on cooking with root vegetables to date. Each vegetable has its own chapter where it is explored in depth. The first few pages of each chapter are dedicated to a vegetable’s history, nutrition information, availability, storage, preparation, and a listing of which varieties a reader may find at their local farmers market or grocery store. From there the vegetable is put through a handful of recipes, as varied and intriguing as any you might find in an entire collection of cookbooks. Morgan digs deep here, drawing from a well of varied influences; you’ll find a whole globe’s worth of inspiration in Roots, as well as your standard American comfort fare.
The thing that made me most giddy about Roots, though, is that Morgan has included root spices interspersed with the standard tubers and other root vegetables most Americans are used to pulling out of the ground. Ginger, wasabi, turmeric, galangal, and others celebrate inclusion with their own chapters, and I can tell you with all certainty that you’ve not lived until you’re tried Morgan’s Chocolate-Galangal Crinkle Cookies or her Wasabi-Crusted Roast Beef Tenderloin.
What was the most valuable thing I learned from this book? Turns out, I was woefully unaware of the depths to which roots vegetables’ versatility traveled. I discovered that they can braised like a meat, candied like fruit, and turned into any number of delectable desserts that even the most vile veggie-hater can be tempted into enjoying. Morgan’s handful of sweet dishes were the most surprising, and I was delighted to find recipes for Brown Sugar Ginger Ice Cream, Red Velvet Beet Cupcakes with Orange Buttercream, and a lovely Ginger Cake with Crème Anglaise. (Anyone who loves red velvet will celebrate the opportunity to completely remove the caustic taste of red food coloring from their cake.)
Below you’ll find the recipe from Roots I most enjoyed, a three-layer parsnip cake with cream cheese frosting. Those of you who make an autumn carrot cake every year may be smacking your head and saying, “Oh, yes, that makes sense,” much like I did. I am happy to report that we carrot cake lovers can now change up our repertoire a bit by engaging the humble parsnip, an sadly undervalued vegetable. I like parsnips, but even in my cooking rotation parsnips have been relegated to nothing more than a stock flavorant and occasional addition to a hearty winter stew. I’m grateful for the inspiration to change that up.
I highly recommend Roots: The Definitive Compendium with more than 225 Recipes for anyone who is at all interested in exploring the topic of root vegetables with any level of creativity. Diane Morgan has managed to elevate our most taken for granted class of produce to a level of intrigue, and that is no easy feat.
- Ingredients for cake:
- Unsalted butter for the cake pans, at room temperature
- 2 cups/255 g all-purpose flour, plus more for dusting the pans
- 2 teaspoons baking powder
- 2 teaspoons baking soda
- 2 teaspoons ground cinnamon
- 1 teaspoon kosher or fine sea salt
- 1/2 teaspoon freshly ground nutmeg
- 3 cups/680 g grated parsnips, about 8 trimmed and peeled parsnips (see Cook’s Note)
- 1 cup/85 g sweetened flaked dried coconut
- 1 cup/115 g chopped walnuts
- 1/2 cup/85 g golden raisins
- 2 cups/400 g granulated sugar
- 1 cup/240 ml canola or other neutral oil
- 4 large eggs
- Ingredients for cream cheese frosting:
- Two 8-ounce packages cream cheese, at room temperature
- 1 cup/225 g unsalted butter, at room temperature
- 2 cups/200 g confectioners’ sugar, sifted
- 1 tbsp fresh lemon juice
- 1/2 cup/40 g sweetened flaked coconut for garnish (optional)
- Cake recipe method: Position one rack in the center and a second rack in the lower third of the oven and preheat to 350°F (176°C). Butter three 9-in/23-cm cake pans with 1½-in/4-cm sides. Line the bottom of each pan with a circle of parchment paper. Butter the parchment paper. Sprinkle one pan with a spoonful of flour, and then tilt and tap the pan to distribute the flour evenly. Turn the pan upside down over the sink and gently shake out the excess flour. Repeat with the second and third pans.
- In a large bowl, sift together the flour, baking powder, baking soda, cinnamon, salt, and nutmeg. In another bowl, stir together the parsnips, coconut, walnuts, and raisins.
- In a stand mixer fitted with the paddle attachment, or in a large bowl using a handheld mixer, beat together the sugar and oil until smooth, about 2 minutes. Begin the mixer on low speed and then increase to medium speed so the oil doesn’t splatter. Add the eggs, one at a time, beating well after each addition until the batter is smooth. On low speed, add the flour mixture and beat just until it disappears. Using a rubber spatula, fold in the parsnip mixture until evenly distributed.
- Divide the batter among the prepared pans, spreading it evenly in each pan. Bake the cakes until they just start pulling away from the sides of the pan and a toothpick inserted into the center of a cake comes out clean, 40 to 50 minutes. For even baking, at the midpoint, switch the pans between the racks and rotate them front to back. Let the cakes cool in the pans on wire racks for 15 minutes. Run a table knife around the inside edge of each pan to loosen the cake sides. Invert the cakes onto the racks and peel off the parchment paper. Let cool completely before frosting.
- Frosting recipe method: In a stand mixer fitted with the paddle attachment, or in a large bowl using the handheld mixer, beat the cream cheese on medium speed until smooth, about 3 minutes. Add the butter and beat until combined, about 2 minutes. Add the confectioners’ sugar and lemon juice and beat until fluffy, about 3 minutes.
- Place one cake layer, top-side down, on a cake plate. Using an offset spatula, spread one-third of the frosting over the top. Spread the frosting right to the edge of the top without frosting the sides. Carefully set the second cake layer on top, placing it top-side down and lining up the edges. Spread half of the remaining frosting on top of the layer the same way. Place the third cake layer on top, right-side up. Spread the remaining frosting over the top of the cake, again without frosting the sides. Swirl the frosting to decorate the top and then garnish the top evenly with the coconut, if desired. Refrigerate the cake for at least 45 minutes to set the frosting. Remove from the refrigerator 30 to 40 minutes before serving.
- Cook’s note: If you have a shredding blade for your food processor, you can make quick work of grating the parsnips. Otherwise, use the coarse holes on a box grater.
