Instructions

Step 1: Preparing the Tempeh Filling

Begin by carefully selecting high-quality tempeh from your local Indonesian market or trusted supplier. Cut the tempeh into small, uniform pieces—about 1/2 inch cubes or smaller—ensuring they are manageable and suitable for frying and mashing. This step is crucial because the size of the tempeh pieces influences the texture of the filling and, ultimately, the bite of the Combro.

In a deep frying pan or wok, heat approximately 1 cup of vegetable oil over medium heat. The oil temperature should be around 160°C to 180°C (320°F to 356°F). Use a thermometer for precision if available, or test with a small piece of tempeh to see if it sizzles immediately upon contact. Carefully add the tempeh pieces into the hot oil, ensuring not to overcrowd the pan—frying in batches if necessary.

Fry the tempeh until it turns golden brown and develops a crispy exterior, about 3-4 minutes per batch. Remove the fried tempeh using a slotted spoon or skimmer, and place on paper towels to drain excess oil. Let it cool slightly before proceeding to mash.

Using a mortar and pestle, or a sturdy fork, mash the fried tempeh until it reaches a crumbly, slightly chunky consistency. This mashed tempeh will serve as a key component of the filling, providing both flavor and texture. Set aside for now.

Step 2: Making the Sambal Tempe Filling

In a clean frying pan, pour about 2-3 tablespoons of oil—preferably a neutral oil like vegetable or canola oil—and heat over medium flame. Add the minced garlic cloves, chopped red chilies, curly chilies, bird’s eye chilies, and kencur. Sauté the mixture, stirring constantly, until fragrant and slightly softened, approximately 2-3 minutes. Be careful not to burn the garlic or chilies; adjust the heat as needed.

Once fragrant, transfer the sautéed ingredients to a mortar and pestle or food processor. Add the grated palm sugar, salt, and bouillon powder if using. Grind or process until it forms a smooth, aromatic paste. The grinding process releases essential oils and intensifies the flavor profile, which is vital for authentic sambal.

In the same pan, add a little more oil if necessary and sauté the paste for another 2-3 minutes until the mixture becomes aromatic and slightly darker. Add the mashed tempeh and chopped basil leaves. Mix thoroughly, ensuring the tempeh is coated evenly with the sambal paste. Taste and adjust seasoning—add more salt, sugar, or chili for desired spice level.

Cook the mixture for an additional 2-3 minutes, allowing the basil to wilt and flavors to meld. Remove from heat and set aside to cool slightly before assembly.

Step 3: Preparing the Dough

Start by peeling the cassava roots carefully with a vegetable peeler or sharp knife. Rinse thoroughly under cold water to remove any dirt or impurities. Using a fine or medium grater, shred the cassava into small, uniform pieces. Hold the grater firmly and use smooth, controlled motions to avoid injury and ensure consistency in texture. Place the grated cassava into a large mixing bowl.

Similarly, grate the coconut if using fresh. If using frozen shredded coconut, thaw it first before mixing. Combine the grated cassava and coconut thoroughly in the bowl. This blend creates a moist, pliable dough that is essential for shaping the Combro.

Add the sliced green onions and salt to the mixture. Green onions provide a subtle onion aroma and flavor that complements the earthy cassava and coconut. Mix everything evenly using your hands or a large spatula, ensuring that all ingredients are well incorporated and the mixture is cohesive but not overly wet.

Step 4: Shaping the Combro

Prepare a clean surface or plate for shaping the combro. Take a handful of the cassava mixture—roughly the size of a golf ball or slightly larger—and flatten it into the palm of your hand, creating a small, thin disc. Be gentle but firm to prevent tearing or cracking.

Place a spoonful of the cooled sambal tempe filling in the center of the flattened dough. Use the back of the spoon to create an indentation or well in the center of the dough, accommodating the filling comfortably without overflowing.

Carefully fold the edges of the dough over the filling, pinching and sealing to enclose the sambal completely. Shape the filled dough into a round, flat patty about 2-3 inches in diameter and approximately 1/2 inch thick. Ensure that the edges are well sealed to prevent filling leakage during frying.

Repeat this process with the remaining dough and filling, maintaining a consistent size and shape for uniform frying and presentation. If the dough becomes sticky or difficult to handle, lightly dust your hands with a little rice flour or water to ease shaping.

Step 5: Frying the Combro

Heat a generous amount of oil—about 2-3 inches deep—in a deep frying pan or wok over medium heat. The oil temperature should be maintained at approximately 170°C (340°F). Use a thermometer for accuracy or test the oil by dropping a small piece of dough; if it sizzles and rises quickly to the surface, the temperature is right.

Carefully place the shaped combro into the hot oil, avoiding overcrowding to prevent drastic temperature drops. Fry in batches if necessary, ensuring each piece has enough space to cook evenly.

Fry the combro for about 4-5 minutes, flipping occasionally with tongs or a slotted spoon to achieve an even, golden-brown crust. The exterior should be crispy and firm, with a slight puffiness indicating thorough cooking.

Use a slotted spoon or skimmer to remove the combro from the oil once golden and crispy. Drain on paper towels or a wire rack to remove excess oil and maintain crispness.

Step 6: Serving and Presentation

Arrange the fried Combro on a serving platter lined with parchment or a decorative plate. Serve hot and crispy to enjoy the full contrast of textures and flavors. These should be eaten fresh for maximum crunch and aroma, but they can be kept warm in a low oven if needed.

Offer accompanying dipping sauces such as sweet chili sauce or a spicy soy-based dip for added flavor. Garnish with additional fresh basil or sliced chilies if desired to enhance visual appeal and taste.

Preparation Tips

• Consistent size and shape: Using a cookie scoop or small ice cream scooper can help achieve uniformity, ensuring even frying and presentation.
• Control oil temperature: Maintaining a steady temperature prevents overly greasy or undercooked combro. Use a thermometer for precise control.
• Sealing the edges: Properly sealing the dough edges prevents filling leakage and maintains the structural integrity during frying.
• Frying in batches: Avoid overcrowding, which can cause temperature drops and uneven cooking. Fry in small batches for best results.
• Cooling before frying again: Let the shaped and filled dough rest for 5 minutes before frying to help set the shape and reduce oil splatter.

Nutritional Information

Values are approximate and depend on portion size and specific ingredients used. For detailed nutritional analysis, consider using specialized software or consulting a nutritionist.

Tips and Tricks

• Use fresh ingredients: Fresh basil, chilies, and cassava contribute significantly to authentic flavor and texture.
• Adjust spiciness: Control the heat by modifying the quantity and type of chilies used. Bird’s eye chilies are very spicy—use less if you prefer milder flavors.
• Enhance flavor: Add a splash of coconut milk to the cassava dough for a richer taste and softer texture.
• Make ahead: Prepare the filling and dough in advance, assemble, and refrigerate for up to 24 hours. Fry just before serving for optimal crunch.
• Freezing: Shape and freeze raw combro on a tray. Once frozen, transfer to an airtight container. Fry directly from frozen for quick snacks.

Add-ons and Variations

• Cheese filling: Incorporate grated cheese into the sambal tempe for a creamy twist.
• Vegetables: Add finely chopped carrots or bell peppers into the filling for added nutrition and color.
• Spice levels: Experiment with different chili blends or add a dash of paprika for smoky flavor.
• Serving dips: Offer peanut sauce, sweet chili, or sambal matah as dipping options.

Side Dishes

Complement Combro with a variety of Indonesian side dishes such as:

• Ketupat or steamed rice cakes
• Gado-gado salad with peanut sauce
• Sambal goreng kentang (spicy fried potatoes)
• Fresh vegetable slices and acar (pickled vegetables)
• Fried tempeh or tahu (tofu)

Improvements

For an upgraded version, consider:

• Adding a layer of grated cheese or a slice of mozzarella inside the filling for gooeyness.
• Using a mixture of different chilies to achieve a complex heat profile.
• Incorporating finely chopped shallots or lemongrass into the sambal for extra aroma.
• Deepening the flavor with a splash of fish sauce or soy sauce in the filling (if non-vegetarian).

Save and Store

To store leftover Combro:

• Place cooled pieces in an airtight container lined with paper towels to absorb any residual oil.
• Refrigerate for up to 3 days. Reheat in a hot oven (180°C) or on a skillet for crispiness.
• For longer storage, freeze uncooked shaped Combro on a baking sheet, then transfer to a sealed bag. Fry directly from frozen, adding an extra minute to cooking time.

FAQ

Can I make the dough gluten-free?

Yes. The traditional recipe uses grated cassava and coconut, which are naturally gluten-free. Ensure all additional seasonings are free from gluten contamination.

Can I bake instead of fry?

Baking is possible, but it will not replicate the crispy texture achieved through frying. To bake, preheat oven to 200°C, place shaped Combro on a baking sheet lined with parchment, and bake for 20-25 minutes, flipping halfway through. For optimal crispiness, finish with a quick broil.

How spicy is this recipe?

The level of spiciness depends on the amount and type of chilies used. Adjust according to your preference, starting with fewer bird’s eye chilies and increasing gradually.

Is there a vegetarian or vegan version?

Yes. Use plant-based tempeh and ensure no animal-derived ingredients are added. Coconut milk or vegetable oil can be used for richness.

What is the best oil for frying?

Use neutral oils with high smoke points such as vegetable, canola, or rice bran oil for best results and safety.
