Kumquat Grand Marnier Cake with Rosemary Lemon Glaze

If I could only have one fruit for the rest of my life, it’d be the orange.

Think about it — it’s food and juice. It’s sweet and tart. You can candy the peel or spritz it into a cocktail. The pith adds a welcome bitterness if you want to change it up.

Kumquats are like super-charged oranges, which make them perfect as pops of contrasting flavor in a rich cake. Because you can eat the skin, you get the bitterness along with juice, sweet, and tart.

To me, kumquat is a very adult flavor because of its mouth-puckering flavors. Adult taste, adult beverage, so I added a healthy dose of Grand Marnier to soak the kumquats. Rosemary amps up the somewhat savory notes of kumquat and adds a lovely aroma — if the kumquats and booze weren’t doing that already.

RECIPE

1 3/4 cup kumquats
1/2 cup Grand Marnier

2 cups flour
1 teaspoon baking soda
1 teaspoon baking powder
pinch of kosher salt

1 1/2 stick butter, room temperature
1 cup granulated sugar

3/4 cup Greek yogurt

3/4 cup powdered sugar
2 tablespoons lemon juice
6 sprigs rosemary

Thinly slice the kumquats and add to a medium bowl. Pour the Grand Marnier over them and allow to soak. Preheat oven to 350°F. Butter and flour a 9-inch bundt pan.

Mix the flour, baking soda, baking powder and salt in a large bowl and set aside.

In an electric mixer, cream the butter and sugar on medium-high until light and fluffy. Add the eggs one at a time and mix until incorporated. Reduce mixer speed to low and add one-third of the flour, then half the yogurt, then one-third the flour, then the rest of the yogurt, then the rest of the flour. Add kumquats and Grand Marnier.

Gently pour into prepared Bundt pan and smooth out top, careful not to the smoosh the fluffiness. Bake for 60 minutes, rotating midway.

Remove cake from oven and immediately start making glaze. Mash three sprigs of rosemary with the lemon juice. Strain, then add infused juice to powdered sugar. Mix thoroughly. You will think you need more liquid, but you don’t. Keep mixing until you reach a stiff but still fluid consistency. Invert Bundt pan onto wire rack on top of a baking sheet (to catch the dripping glaze). Immediately pour glaze on top and top with the rest of your crushed rosemary. The cake must be glazed while the cake is hot, so work fast!

Kumquat Carrot Cake Muffins

Like clockwork. Every time the weather warms up a little, I get an urge to bake. 

Am I self-sabotaging before bikini season? Seeking heat inside to match the heat outside? Or maybe...it's all in my head. 

But alas, here we are, daffodils a-peepin', cherry blossoms a-blossomin', and me. A bakin'. 

These came about because D thought he liked kumquats even though I had never seen him eat a kumquat and he doesn't like very sour or bitter things. Nevermind! We bought a whole sackful at a raucous grocery store in Flushing. 

Turns out D doesn't like kumquats... and so we were left with three pounds of kumquats and two stomachs that couldn't quite take them eaten whole. 

So here we are, the kumquat carrot cake muffin. These are strictly more muffin than cake. I wanted to round out the assertiveness of the kumquat while still keeping its essential character -- ie: not throwing a lot of sugar at it. I used coconut and turbinado sugar for texture and a sweet musty complexity. But if sugar is what you want, do it! That's what jam is for. 

RECIPE: 

2 cups kumquats, seeded and sliced

2 tablespoons butter
¼ cup coconut sugar 

¾ cup vegetable oil
⅛ cup white sugar
⅞ cup turbinado sugar
1 teaspoon vanilla extract 

3 large eggs 

2 cups flour
1 teaspoon cinnamon
2 teaspoons baking soda
1 ½ teaspoons kosher salt 

3 cups grated carrots
1 cup raisins
½ cups walnuts (optional) 

Preheat oven to 400 degrees Fahrenheit. Cut and seed the kumquats. Place in saucepan with butter and sugar. Simmer on medium until the kumquats are soft and pliant, about 6 minutes. 

Using the paddle attachment of a mixer, blend the oil, sugars, and vanilla extract. Add eggs one by one until mixed. In a separate bowl, mix the flour, cinnamon, baking soda and salt. While the mixer is on medium, slowly add half the dry ingredients to the wet ingredients. Add the carrots, raisins, and walnuts. Add the rest of the dry ingredients and mix until just blended.

Grease a muffin pan. Spoon the kumquat mixture so it just coats the bottom. Add the carrot cake batter into each cup about 80% full. Bake for 10 minutes at 400 degrees, then reduce to 350. Bake until an inserted toothpick comes out clean. Large muffin tins will bake in about 25-30 minutes. A small muffin tin will bake in about 15-20 minutes. Cool completely before removing from the tin. 

Eat in your preferred fashion. Here I had some with a dollop of Rhubarb and Meiwa Kumquat jam from Sqirl.
