Make the carrot sponge base
Storage: Store in an airtight container in the refrigerator for up to 36 hours
Equipment: microplane, vacuum sealer, oven, quarter sheet pan, parchment paper, medium bowl, stand mixer, whisk attachment, paddle attachment
- 0.5 lbs – carrots (peeled and very finely grated)
Peel and finely grate the carrots with microplane
- 2 gram – Kosher Salt
Vacuum seal carrots and salt, let sit for 30 minutes, gently squeeze to remove excess liquid (carrots should remain moist, not dry)
Preheat oven to 325°F
- neutral oil
Line a quarter sheet pan with parchment paper using the "double sling" method, lightly grease.
- 90 gram – buttermilk
- 49 gram – lillet blanc
- 1 teaspoon – vanilla extract
In a medium bowl, whisk together the buttermilk, lillet blanc, and vanilla extract.
- 100 gram – cake flour
- 2.5 gram – Kosher Salt
- 0.75 teaspoon – baking powder
- 0.25 teaspoon – baking soda
In a separate large bowl, whisk together the flour, baking powder, baking soda, and salt.
- 110 gram – granulated sugar
- 2 count – large eggs
In a stand mixer fitted with the whisk attachment, beat the eggs and sugar on medium-high speed to ribbon stage (until pale, thick, and the batter falls in a ribbon that briefly holds on the surface)
- 20 gram – honey
Drizzle honey in slowly on medium speed while preserving as much volume as possible (do not overmix)
- 100 gram – neutral oil
Emulsify the oil by pouring in a thin stream while mixing on medium speed, reducing to low as the emulsion forms
Using the paddle attachment on low speed, incorporate the dry ingredients in 3 additions, alternating with the wet ingredients, beginning and ending with dry ingredients, until just combined
Incorporating the grated, drained carrots by hand with a spatula, folding gently to avoid deflating the batter
Rest the batter for 10-15 minutes to allow the flour to fully hydrate
Pour the batter into the prepared pan, spread evenly to ~½–¾ inch thickness, and bake for 12–18 minutes, until a cake tester inserted in the center comes out with just a few moist crumbs, and the surface springs back lightly when pressed
Check on the cake frequently after 10 minutes
Let cool completely before handling
