Ingredients

• 300 grams green beans, trimmed
• 120 grams all-purpose flour
• 30 grams cornstarch
• 1 teaspoon baking powder
• 180 milliliters cold sparkling water
• 3 pieces ice cubes
• 1 liter vegetable oil (for frying)
• 2 tablespoons honey
• 1 tablespoon Dijon mustard
• 1 tablespoon apple cider vinegar
• 1 teaspoon soy sauce
• 1 clove garlic, finely minced
• 1 tablespoon water (for sauce)
• 0.5 teaspoon salt
• 0.25 teaspoon black pepper

Directions

Step 1

Prepare the Sweet and Sour Mustard Sauce: In a small bowl, whisk together honey, Dijon mustard, apple cider vinegar, soy sauce, minced garlic, and water until smooth. Season with salt and black pepper to taste. Set aside.

Step 2

Heat the vegetable oil in a deep fryer or large, heavy-bottomed pot to 180°C (350°F). Ensure there's at least 2 inches of oil for frying.

Step 3

Meanwhile, in a large mixing bowl, whisk together all-purpose flour, cornstarch, baking powder, and a pinch of salt.

Step 4

Add the cold sparkling water to the flour mixture, stirring gently until just combined. It's fine if the batter is slightly lumpy—this helps create a light, crispy coating.

Step 5

Place a few ice cubes in the batter to keep it extra cold while frying.

Step 6

Dip the trimmed green beans into the tempura batter, ensuring they are fully coated.

Step 7

Carefully drop a few battered green beans into the hot oil without overcrowding the pot. Fry for 2–3 minutes, or until golden and crispy, turning occasionally with a slotted spoon.

Step 8

Transfer the fried green beans to a paper towel-lined plate to drain excess oil. Repeat with the remaining green beans.

Step 9

Serve the tempura green beans hot with the Sweet and Sour Mustard Sauce on the side for dipping. Enjoy!
