Instructions

Step 1: Prepare the Sambal Filling

Begin by assembling all the ingredients for the sambal filling. The fiery sambal is the heart of Tempe Mercon, providing the spicy kick that defines this dish. Place the red curly chilies, bird’s eye chilies, garlic, shallots, and a small piece of shrimp paste into a dry skillet or frying pan over medium heat. Roast these ingredients, stirring frequently, until they become fragrant, slightly charred, and soft—about 5-7 minutes. The roasting process enhances their flavors and imparts a smoky undertone that complements the heat.

Once roasted, transfer the mixture to a heatproof bowl and allow it to cool slightly. For a smooth filling, blend the roasted ingredients in a food processor or with a hand blender until they form a fine, uniform paste. If you prefer a chunkier texture, pulse the mixture gently or mash with a mortar and pestle.

Season the sambal with salt, sugar, and seasoning to taste. The balance of flavors is crucial—start with small amounts and adjust according to your preference. The sambal should be fiery, savory, and slightly sweet, with a complex depth of flavor that adds a punch to each bite.

Step 2: Prepare the Coating Batter

In a mixing bowl, combine the wheat flour and rice flour. The rice flour adds crispiness, making the outer layer of the tempe more crunchy after frying. Gradually add water while whisking continuously to create a smooth, thick batter. The consistency should be similar to pancake batter—thick enough to coat the tempe evenly but not too runny. Add sliced green onions into the batter for a hint of freshness and aroma.

If the batter is too thick, add a little more water; if too thin, sprinkle in a bit more flour. Rest the batter for a few minutes to allow the flavors to meld and the gluten to relax, which helps in achieving a better coating texture.

Step 3: Prepare the Tempe

Remove the tempe block from its packaging and cut it into evenly sized cubes or rectangles, depending on your preference. For classic bite-sized pieces, about 2-inch squares work well. Carefully make a slit or pocket in the center of each piece, creating space for the sambal filling. Use a sharp knife to avoid tearing the tempe.

Using a small spoon or your fingers, fill each slit with a generous amount of the prepared sambal, ensuring the filling is evenly distributed and pressed firmly inside. Be cautious not to overstuff, which might cause the tempe to burst during frying.

Step 4: Coat the Tempe

Dip each stuffed tempe piece into the batter, turning gently to ensure it’s fully coated on all sides. The batter should adhere well, creating a smooth, even layer that will crisp up during frying. If the batter is too thin, add a small amount of flour; if it’s too thick, add a splash of water to reach the desired consistency.

Place the coated tempe pieces on a plate or tray, ready for frying. To prevent sticking, you can lightly dust the coated pieces with additional rice flour if needed.

Step 5: Fry the Tempe

Heat oil in a deep frying pan or wok over medium heat. The oil should be deep enough to fully submerge the tempe pieces. To test if the oil is ready, drop a small amount of batter into the oil—if it sizzles and rises to the surface immediately, the oil is hot enough.

Carefully place the coated tempe into the hot oil in batches to avoid overcrowding. Fry each batch for about 4-6 minutes, turning occasionally with a slotted spoon or tongs, until they are golden brown and crispy on all sides. Maintain a steady temperature to ensure even cooking; adjusting heat as necessary.

Remove the fried tempe from the oil and drain on paper towels or a wire rack to remove excess oil. Serve hot for maximum crunch and flavor.

Step 6: Serve and Enjoy

Arrange the Tempe Mercon on a serving platter. These spicy stuffed tempe pieces are best enjoyed immediately while crispy and hot. Pair them with a simple cucumber salad, a sweet soy dipping sauce, or a tangy sambal for added flavor and cooling contrast. For an authentic presentation, garnish with additional sliced green onions or sesame seeds.

Preparation Tips

• Adjust the spice level by increasing or decreasing the number of bird’s eye chilies. Milder chilies can be substituted for a less fiery version.
• Use fresh, quality tempe for the best texture and flavor. If unavailable, refrigerated or frozen options can be used but ensure they are properly thawed before preparation.
• For an even crispier coating, double-dip the tempe in batter—dip, fry briefly, then dip again before the final fry.
• Maintain a consistent oil temperature around 170-180°C (340-360°F) for optimal frying results.

Nutritional Information (Per Serving, Approximate)

Tips and Tricks

• For a smoky flavor, add a dash of smoked paprika or roasted garlic to the sambal blend.
• Experiment with different chili varieties to customize the heat level.
• Use a thermometer to ensure the oil stays at the optimal temperature for crispiness.
• Leftover fried tempe can be stored in an airtight container in the refrigerator for up to 2 days; reheat in a hot oven or air fryer for best results.

Add-ons

• Serve with a side of fresh cucumber slices or a simple vegetable salad dressed with lime and salt.
• Pair with Indonesian-style sambal bajak or sambal matah for extra heat and flavor.
• Add a drizzle of sweet soy sauce or kecap manis for a sweet-savory touch.

Side Dishes

• Indonesian rice cakes (lontong or nasi uduk)
• Steamed jasmine rice or coconut rice
• Fresh vegetable salad with lime dressing
• Fried tempe chips or tahu goreng (fried tofu)

Improvements

• Incorporate grated cheese or shredded coconut into the sambal for added richness.
• Make a vegetarian version by replacing shrimp paste with fermented soybean paste or omitting it entirely.
• Add finely chopped herbs like cilantro or Thai basil for extra freshness.

Save and Store

Fried Tempe Mercon is best enjoyed fresh for maximum crispiness. However, leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat in a preheated oven at 180°C (356°F) for 5-7 minutes or use an air fryer to regain crunchiness. Do not freeze, as the coating may become soggy once thawed.

Frequently Asked Questions (FAQ)

Can I make this vegan?

Yes. Simply omit the shrimp paste or replace it with a plant-based fermented chili paste or miso. Ensure the batter and fillings are free from animal-derived ingredients.

Is tempe available worldwide?

Tempe is widely available in Asian markets and health food stores globally. If unavailable, fresh tofu can be used as an alternative, though the texture and flavor will differ.

Can I bake instead of frying?

Baking is possible for a healthier version. Preheat oven to 200°C (392°F), place coated tempe on a baking sheet lined with parchment paper, and bake for 15-20 minutes, flipping halfway through until crispy. The result will be less crispy than frying but still delicious.
