This banana tempura recipe uses vodka and carbonated water to create a light, brittle tempura crust. The batter stays crispy from ice-cold mixing, minimal gluten development, and a drizzle technique that adds craggy texture. Served with a 3-ingredient chocolate ganache that takes less than 5 minutes.
Heat the heavy cream and corn syrup in a small saucepan over medium-high heat until a skin forms on top and the mixture is just under a boil.
Pour the hot cream mixture over the chocolate. Allow it to sit for 1-2 minutes.
Stir until the chocolate is completely melted and incorporated into the cream.
Let the ganache cool, then store in a covered container in the fridge for up to one week. Reheat in the microwave in 10-20 second increments before serving.
Prep the Bananas
Cut each banana in half diagonally, then slice each half lengthwise down the middle. You should have four pieces per banana.
Set Up the Frying Station
Line a baking sheet with a double layer of paper towels.
Heat about 2 inches of vegetable or canola oil in a large stockpot to 325°F (165°C). Use a deep fry or infrared thermometer to verify the temperature.
Mix the Tempura Batter
Fill the bottom of a medium bowl with ice and set aside.
In a small bowl, combine the all-purpose flour, cornstarch, and kosher salt. Stir until evenly distributed.
In another bowl, whisk together the egg, vanilla extract, and vodka until completely homogenous. Stir in the ice-cold carbonated water.
Pour the wet mixture over the dry ingredients. Using chopsticks or a fork, lightly stir until just barely combined. The batter should be lumpy with some dry spots. Do not overmix.
Place the batter bowl on top of the bowl of ice to keep it cold.
Fry the Banana Tempura
Dust the banana slices in powdered sugar.
Dip the banana slices into the tempura batter and lift, allowing excess batter to drip off.
Slowly lower the battered banana slices into the hot oil.
Using your hand, carefully drizzle extra tempura batter onto the frying banana slices. Do not hold the batter bowl directly over the oil.
Flip the pieces several times while frying. Total fry time is 1.5-2 minutes.
Lift the banana slices out of the oil, allowing excess oil to drip off. Place on the paper towel-lined baking sheet.
Dust the fried banana tempura with powdered sugar while still hot.
Plate and Serve
Arrange the banana tempura on a plate.
Drizzle with warm chocolate ganache.
Dust with additional powdered sugar and serve with a scoop of ice cream.

Notes
Vodka in the Batter: Vodka limits gluten development and reduces water absorption in the flour. Both produce a lighter crust. The alcohol evaporates completely during frying. If you prefer not to use vodka, substitute an equal amount of additional carbonated water.Cake Flour vs. All-Purpose Flour: Cake flour has less protein than all-purpose, which means less gluten and a more delicate crust. All-purpose will work if that's what you have.Banana Ripeness: Use bananas that are just barely ripe, yellow with maybe a hint of green at the tips. Too green and they'll be bland. Too ripe and they'll turn to mush in the fryer.Oil Temperature: 325°F is lower than most frying recipes. Higher temperatures will turn the banana to mush before the crust sets. Lower temperatures cause the batter to absorb oil. Use a thermometer.The Drizzle Technique: After lowering the battered banana slices into the oil, drizzle extra batter over them by hand. Don't hold the batter bowl directly over the oil. This creates the craggy, textured crust.Chocolate Ganache Storage: The ganache stores in a covered container in the fridge for up to one week. Reheat in the microwave in 10-20 second increments before serving.
