I made this Thai-inspired blueberry lemongrass pound cake to celebrate Nancie McDermott, whose heart is in two places, the American South and Thailand. Pound cake, a southern favorite, gets a Thai jolt with fresh lemongrass, coconut milk and fresh ginger. You will need to prepare the lemongrass/coconut milk mixture 6 hours before baking if not the day before, so plan accordingly.
4-5fresh lemongrass leaves, about 2-2/12 feet long(See Note below)
13ozcake flour
1teaspoonbaking powder
19ozgranulated sugar
12ozexcellent quality unsalted butter at cool room temperature(I used Stirling Churn 84--See Note below)
1 ¼teaspoonsfine sea salt
zest of 2 lemons
1full teaspoon of freshly minced ginger(use a microplane for extra-juicy, finely grated ginger)
5large eggs, beaten and at cool room temperature.
⅔cupfresh or frozen(do not thaw) blueberries
For the Glaze (optional but lovely)
1 ½cupspowdered sugar, sifted
pinchof salt
Enough coconut milk to yield a nice drizzling consistency, about 2-3 Tablespoons or so
Instructions
To Prepare the Lemongrass/Coconut Milk Mixture
Wash the lemongrass leaves and cut into about 1" lengths. Put them in a container with a tight-fitting lid and pour in the can of coconut milk.
Shake the container well and leave in the fridge for about 5-6 hours, shaking well when you think about it.
To Make the Cake
Spray and flour a 12 cup Bundt pan. Set aside.
Set an oven rack in the bottom third of the oven. Preheat oven to 325F.
Put the coconut milk and lemongrass leaves into your blender and blend on high speed for about 20-30 seconds, until the milk is a pale green and the leaves are very finely shredded.
Strain the mixture, pressing down on the solids, and weigh out 11 oz**(See the Butter note below). Set aside.
Whisk the flour and baking powder together really well. Set aside.
In the bowl of your stand mixer fitted with the paddle attachment, cream butter until it is smooth.
Add the sugar, salt and lemon zest and cream well until light and fluffy (about 10 minutes). Scrape bowl as necessary.
Add the ginger and blend until evenly combined.
With the mixer on medium-low speed, drizzle in the egg a bit at a time, allowing one addition to mix in completely before adding more. This will take about 5-7 minutes. Scrape bowl as necessary.
Add 1/2 of the dry ingredients to the bowl. Mix on low speed for about 5 seconds. Flour will not be completely incorporated.
With the mixer still running on low, pour in half the coconut milk and mix for a few seconds. Milk may not be completely incorporated. Scrape the bowl.
Repeat with the remaining half of the flour, the rest of the coconut milk and finish with the last of the flour.
Scrape the bowl and then fold the batter to make sure the flour and coconut milk are completely incorporated.
Spread 2/3 of the batter evenly into the pan and top with half the blueberries. You can toss them with a bit of flour first. This might prevent them from sinking. Or not. Either way, it's okay.
Spread in the remaining batter and top with the rest of the blueberries (they will sink in. If you're lucky, they won't make it all the way to the bottom. Don't be sad if they do, though).
Bake for about an hour, or until a tester comes out clean, the top is a deep golden brown and the cake is just starting to pull away from the sides of the pan. The internal temperature of the cake should be right around 200F.
Remove from the oven and let cool in the pan for 30 minutes before turning out on a cooling rack. For super moist cake, you can wrap it immediately in plastic wrap and let it cool that way. For regular moist cake, just leave it alone and let it cool.
If using the glaze, drizzle it on at least an hour before slicing and serving so it will have time to set up.
For the Optional Glaze
Whisk the sugar, salt and 1 1/2 Tablespoons of coconut milk together. Add more coconut milk, just a bit at a time, until you like the consistency. For my glazes, I like them to be a bit thicker than honey and run very slowly off the whisk. Make yours whatever consistency you prefer.
Notes
If you don't have or can't find fresh lemongrass, use a 4" piece of lemongrass stalk from the store. They're really hard and fibrous, so bruise it up really well with a mallet. Unless you have a Super Blender (like Blendtec or Vitamix) I would skip the blending and just let the mixture steep until you have a deep, lemongrassy flavor. Churn 84 is a high butterfat butter. You can also substitute regular unsalted butter. Reduce the liquid in the recipe from 11 oz to 10 oz.
