Method
Bring a large pot of salted water to a boil. Blanch the halved Brussels sprouts for 2 minutes to soften their dense cores. Immediately transfer them to an ice bath to halt the cooking process. Drain well.
Thoroughly pat the blanched Brussels sprouts, green beans, and scallions completely dry using paper towels. Moisture is the enemy of a crisp crust.
Pour the neutral oil into a heavy-bottomed Dutch oven, ensuring it is no more than half full. Attach a deep-fry thermometer and heat the oil to 185°C (365°F) over medium-high heat. Set a wire rack over a baking sheet nearby.
In a large mixing bowl, whisk together the cornmeal, 125g of all-purpose flour, baking powder, baking soda, kosher salt, and garlic powder. Pour in the cold buttermilk and whisk gently until just combined. Let the batter rest for 5 minutes.
Toss the dried vegetables in the remaining 30g of all-purpose flour to create a dry surface for the batter to grip. Shake off any excess flour, then dip a handful of vegetables into the batter, allowing excess to drip back into the bowl.
Carefully lower the battered vegetables into the 185°C (365°F) oil using a spider skimmer. Fry in small batches to avoid dropping the oil temperature. Cook for 2 to 3 minutes, turning occasionally, until the batter is deeply golden and puffed.
Transfer the fried vegetables to the prepared wire rack to drain. Immediately sprinkle with flaky sea salt while the residual surface oil is hot so the salt adheres. Allow the oil to return to 185°C (365°F) before frying the next batch. Serve hot.
Chef's Notes
- Hydrating the cornmeal for just 5 minutes before frying is crucial; it ensures the batter is fluffy rather than gritty on the palate.
- Blanching the Brussels sprouts slightly softens their dense core. Without this step, they would remain too raw in the center during the short frying time required for the batter.
- Always salt fried foods the moment they emerge from the oil. The residual surface heat and oil help the salt stick securely to the crust.
- Using cold buttermilk limits gluten development in the flour, which keeps the crust crisp and tender rather than chewy and dense.
Storage
Refrigerator: 2 days — Loses crispness quickly. Store in an airtight container lined with paper towels.
Reheating: Preheat oven to 200 degrees Celsius (400 degrees Fahrenheit). Spread on a wire rack over a baking sheet and heat for 5 to 8 minutes until re-crisped. Do not microwave.
