Tart and savory with just a hint of sweetness, this luscious cake gains body and complexity from extra virgin olive oil combined with cultured butter, pastured eggs, freshly-squeezed lemon juice, rosemary and raw honey. Try it topped with homemade mascarpone or a simple lemon glaze..
For the Mascarpone
1 pint raw, fresh cream (ultra-pasteurized cream will not work)
1 tablespoon fresh lemon juice
1 tablespoon filtered water
Heat the cream in a double-boiler until it reaches 185 degrees. Mix water and lemon juice and add to the cream; it should thicken right away. Keep mixture at 185 degree for a full 5 minutes, stirring occasionally.
Transfer mixture to a bowl, cover and refrigerate overnight. Transfer to a cheesecloth-lined strainer set over a clean bowl, refrigerate allow allow to separate 12-24 hours. Mascarpone will keep in the refrigerator for about 1 week.
For the Cake (adapted from a recipe by Ina Garten)
1 cup organic AP flour
1/2 cup sprouted spelt flour
4 oz cultured butter at room temperature
1/4 cup raw honey
2 large pastured eggs at room temperature
1/4 teaspoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon sea salt
3/4 cup freshly squeezed lemon juice, divided
3/4 cup extra virgin olive oil
2 tablespoons fresh rosemary, coarsely chopped
1/4 cup preserved lemon peel, minced
Cream the butter and honey together in a bowl until fluffy. Beat in the lemon peel and eggs, one at a time.
Sift together the flours, baking powder & soda and salt in a bowl. Combine the olive oil and lemon juice in another bowl and alternately add the flour and oil mixtures to the honey butter mixture.
Lightly grease an 8×8 glass dish with olive oil, then pour in the batter and smooth with a spatula. Bake in a 350-degree oven until a toothpick comes out clean, about 40 minutes.
Let cake cool at least 15 minutes, then serve topped with mascarpone and garnished with slivered lemon peel and a sprig of rosemary.
