Ingredients

Tempeh and Batter

Chili sauce

  • ¼ cup kecap manis Indonesian sweet soy sauce
  • 4 bird’s eye chilies thinly sliced
  • 2 cloves garlic minced
  • 2 tablespoons rice vinegar
  • 1 tablespoon chives or scallions minced

Optional Garnishes

  • Lettuce leaves
  • Thinly sliced bird’s eye chilies
  • Cilantro leaves
  • Thinly sliced scallions
  • Bean sprouts
  • Lime wedges

Instructions

  • Heat your preferred frying oil in a pan or Dutch oven to 350°F (175°C). If you have one, I recommend using a frying thermometer to get the oil to an accurate temperature.
  • In a bowl, whisk together all-purpose flour, rice flour, baking powder, white pepper, garlic powder, sugar, coriander, salt, minced garlic, sliced bird’s eye chilies, scallions, and water. Mix until a smooth batter forms.
  • Dip each tempeh fillet into the batter, ensuring an even coating.
  • Fry the coated tempeh until it achieves a golden brown, and crispy texture. Use a slotted spoon or tongs to remove and drain excess oil.
  • In a separate bowl, prepare the chili sauce by mixing the kecap manis, sliced bird’s eye chilies, minced garlic, rice vinegar, and minced chives.
  • Arrange the fried tempeh on a plate over lettuce leaves, drizzle with the chili sauce, and garnish with optional toppings like thinly sliced bird’s eye chilies, cilantro leaves, and scallions.

Notes

💨Air Frying: 
Preheat your air fryer. 
Spray the basket of your air fryer liberally with cooking spray
Coat the tempeh fillets with a thin layer of the batter. 
Arrange the coated tempeh pieces in a single layer in the air fryer basket.
Air Fry at 375°F (190°C) for about 10-12 minutes, flipping halfway through, until the tempeh is crispy and golden brown.
🌡️ Tempering the Tempeh:
Ensure tempeh is at room temperature before battering, as the batter will adhere to it better. 
🧃 Extra Juiciness needed?
If your tempeh is sorta dry and lifeless looking (many Western brands arent spectacular), boil it for 8 minutes in flavorful broth for juiciness, and when cool cut the tempeh into natural, irregular shapes before battering and frying.
🔥 Oil Temperature Precision:
Maintain a steady 350°F (175°C) oil temperature. Use a reliable thermometer for a consistent, crispy finish, avoiding undercooking or excessive browning.
Patience in Frying:
Avoid overcrowding the pan. Fry tempeh in batches, allowing ample space for even cooking. Resist the urge to rush.
