Ingredients

Instructions

  1. Step 1: In a bowl, whisk together 1 cup all-purpose flour, 1/4 cup cornstarch, and 1/2 tsp baking powder. Add 1 egg yolk and 1 cup ice-cold sparkling water, stirring gently until just combined; batter should be lumpy and cold.
  2. Step 2: Heat 4 cups vegetable oil in a deep pot or fryer to 350°F (175°C).
  3. Step 3: Pat dry 12 oz fresh green beans with paper towels. Dip green beans into the tempura batter one handful at a time, allowing excess batter to drip off.
  4. Step 4: Carefully lower the battered green beans into the hot oil in batches, frying for 2-3 minutes until golden and crisp. Remove with a slotted spoon and drain on paper towels.
  5. Step 5: In a small bowl, mix 1/3 cup mayonnaise, 1 tbsp Sriracha sauce, 1 tsp lemon juice, 1/2 tsp salt, and 1/4 tsp black pepper until smooth.
  6. Step 6: Serve tempura-fried green beans hot with the spicy aioli for dipping.
