Method
Preheat the oven to 160C (325F) fan-forced or 175C (350F) conventional.
Grease the interior surfaces of a 20 cm round springform pan with butter and line the bottom neatly with baking parchment paper.
Using a fine zester, zest 2 whole lemons to yield 10 g of bright zest, then juice the lemons to yield 30 ml of strained juice for the batter and reserve any remainder.
In the bowl of a stand mixer fitted with the paddle attachment, cream 200 g softened unsalted butter, 175 g caster sugar, and 10 g lemon zest on medium-high speed for 4 minutes until pale, airy, and fluffy.
With the mixer running on medium-low speed, pour in 150 g lightly beaten room-temperature eggs in three separate additions, beating for 30 seconds after each pour until completely emulsified.
In a separate bowl, stir together 200 g ground almonds, 100 g fine polenta, 5 g baking powder, and 2 g fine sea salt until uniform.
Using a silicone spatula, gently fold the dry almond-polenta mixture and 30 ml lemon juice into the creamed butter base in two additions until no dry pockets remain.
Transfer the cake batter into the prepared springform pan and smooth the top evenly toward the edges using the silicone spatula.
Bake the cake at 160C (325F) fan-forced or 175C (350F) conventional for 40 to 45 minutes, verifying that an instant-read digital food thermometer inserted into the center reads at least 95C (203F), safely surpassing the standard 71C (160F) egg doneness threshold.
While the cake finishes baking, combine 60 g honey, 30 ml strained lemon juice, and 30 ml water in a small saucepan over medium heat, bringing the mixture to a gentle simmer for 3 minutes until slightly reduced and smooth.
Immediately upon removing the cake from the oven, prick the hot surface all over with a cake tester and spoon the warm honey-lemon drizzle evenly across the top.
Set the cake pan on a wire cooling rack to cool for 30 minutes, then release the springform collar and allow the cake to cool completely to room temperature before slicing.
Chef's Notes
- Polenta grind size dictates the final crumb texture; always select finely ground polenta or Italian fioretto rather than coarse bramata to avoid an overly gritty mouthfeel.
- Rubbing the freshly grated lemon zest into the caster sugar with clean fingertips before creaming frictionally ruptures citrus oil glands, yielding vastly superior aromatic distribution.
- Applying warm drizzle to a piping-hot cake optimizes syrup absorption; matching thermal states ensures the liquid draws evenly toward the center without waterlogging the crust.
- This cake improves noticeably after 12 to 24 hours of resting as the cornmeal hydrates completely and the citrus oils equilibrate with the rich almond fats.
Storage
Refrigerator: 5 days — Store in an airtight container to preserve moisture and aroma.
Freezer: 2 months — Freeze unglazed or glazed cake tightly wrapped in parchment and foil. Thaw overnight in the refrigerator.
Reheating: Serve at room temperature or warm individual slices in a 150C (300F) oven for 5 minutes until just warm.
Troubleshooting
Batter curdles and looks split while adding eggs
Cause: Eggs were too cold, shocking the softened butter and breaking the suspension
Fix: Fold in 2 tablespoons of the measured ground almonds and beat on medium speed to restore emulsion
Prevention: Bring eggs and butter to identical room temperature around 20C (68F) before beginning
Center of the cake sinks after removing from the oven
Cause: Cake was underbaked in the center or the oven door was opened prematurely during the initial rise
Fix: Cannot be fixed structurally, but applying the honey drizzle and garnishing with powdered sugar will disguise the surface
Prevention: Keep the oven door closed for the first 35 minutes and confirm the internal core temperature reaches at least 95C (203F)
Finished cake has an unpleasantly gritty, hard crunch
Cause: Coarse bramata polenta or stoneground cornmeal was used instead of fine-milled flour
Fix: Cannot be fixed immediately; wrap the cooled cake tightly for 24 hours to let internal moisture soften the grain
Prevention: Select fine-milled polenta labelled fioretto or fine yellow corn flour
Cultural Context
Originating in Northern Italy, polenta cakes celebrate the agricultural staples of Lombardy and Veneto, where ground maize and orchard nuts traditionally stood in for wheat flour. The harmonious marriage of nutty almond meal, textured cornmeal, and fragrant Mediterranean citrus became a regional icon, cherished worldwide as an inherently gluten-free classic.
