Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Preheat your oven to 175°C. Grease and line a 23cm round cake tin with parchment paper. Ensure your butter and eggs are at room temperature for optimal incorporation and cake texture.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. The proper measurement and mixing of these dry ingredients ensure the cake will have the correct rise and structure.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>In a large bowl or stand mixer fitted with the paddle attachment, cream the butter and sugar on medium-high speed for 4-5 minutes until pale and fluffy. This extended beating incorporates air into the batter, creating a lighter texture and finer crumb.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Add the eggs one at a time, beating well after each addition. Make sure each egg is fully incorporated before adding the next to maintain an emulsion that prevents the batter from separating.</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Add the lemon zest and vanilla extract, mixing until combined. The oils in the zest will release more readily into the fat-containing butter mixture, maximizing flavor distribution throughout the batter.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>In a separate small bowl, combine the lemon juice, buttermilk, and vodka. The acidity in the lemon and buttermilk will react with the baking soda, providing additional leavening for a tender crumb.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Gradually add the dry ingredients to the butter mixture in three additions, alternating with the lemon-buttermilk-vodka mixture, beginning and ending with the dry ingredients. Mix on low speed just until combined after each addition. Overmixing activates gluten and can result in a tough cake.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Pour the batter into the prepared cake tin, smoothing the top with a spatula. Tap the tin gently on the counter a few times to remove any large air bubbles that could create tunnels in your cake.</li><li class="MethodStepper"><h4 class="step-title">Step 9</h4>Bake for 45-50 minutes or until a cake skewer inserted into the center comes out clean with a few moist crumbs. The cake should spring back when lightly pressed and be pulling away slightly from the sides of the tin.</li><li class="MethodStepper"><h4 class="step-title">Step 10</h4>While the cake bakes, prepare the vodka-lemon syrup. In a small saucepan, combine sugar and lemon juice. Bring to a simmer over medium heat, stirring until the sugar dissolves completely. Remove from heat and stir in the vodka. Set aside to cool slightly.</li><li class="MethodStepper"><h4 class="step-title">Step 11</h4>For the candied lemons, bring water and sugar to a gentle simmer in a wide saucepan. Add the lemon slices in a single layer and simmer for 15 minutes until the rinds become translucent. Carefully remove with a slotted spoon and place on a parchment-lined tray to cool.</li><li class="MethodStepper"><h4 class="step-title">Step 12</h4>When the cake is done, let it cool in the tin for 10 minutes, then turn out onto a wire rack placed over a baking sheet to catch drips. While still warm, poke holes all over the top of the cake with a skewer or toothpick.</li><li class="MethodStepper"><h4 class="step-title">Step 13</h4>Brush the warm cake with the vodka-lemon syrup, allowing it to soak in between applications. Use all the syrup; it may seem like a lot, but this creates the signature moist texture and infuses the cake with the cocktail flavor.</li><li class="MethodStepper"><h4 class="step-title">Step 14</h4>Once the cake has cooled completely, prepare the glaze by whisking together the icing sugar and lemon juice until smooth. Add vodka if using. The glaze should be thick but pourable - adjust consistency with more sugar or juice as needed.</li><li class="MethodStepper"><h4 class="step-title">Step 15</h4>Pour the glaze over the center of the cake, allowing it to drip naturally down the sides. Work quickly as the glaze will begin to set. Arrange the candied lemon slices on top in a decorative pattern before the glaze sets completely.</li><li class="MethodStepper"><h4 class="step-title">Step 16</h4>Allow the glaze to set for at least 30 minutes before serving. This cake is best enjoyed the day after baking when the flavors have had time to meld and develop. Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.</li></ol>
