Instructions

1. Preparing the Blood Cockles

Begin by cleaning your blood cockles thoroughly to ensure the removal of any grit, dirt, or sand that may be embedded within the shells. Place the blood cockles in a large bowl filled with cold water, add a generous amount of salt, and swirl gently. Allow them to soak for at least 30 minutes, changing the water once or twice to facilitate cleaning. This process helps to purge any residual sand and impurities from the shells.

Next, transfer the cleaned blood cockles into a large pot. Add one glass of water, a half teaspoon of salt, and the bay leaves. Bring the mixture to a boil over medium-high heat. Once boiling, reduce the heat and cook for about 5 minutes or until the cockles are halfway open and the shells are slightly firm but not fully cooked. This partial cooking prepares the cockles for frying and further flavor infusion during stir-frying.

Remove the cockles from the heat, strain, and set aside. Discard the cooking water and bay leaves. The pre-cooked blood cockles are now ready for frying and incorporating into the flavorful stir-fry.

2. Preparing the Tofu

Select firm or extra-firm tofu for this dish, as it holds its shape well during frying. Cut the tofu into cubes approximately 1-inch in size—uniform pieces ensure even cooking and flavor absorption.

In a frying pan or wok, heat about 2-3 tablespoons of cooking oil over medium heat. Once hot, add the tofu cubes and fry them until they develop a crisp, golden-brown exterior. Turn the cubes gently to ensure all sides are evenly fried. This process typically takes about 4-6 minutes.

Remove the fried tofu with a slotted spoon or spatula and place on paper towels to drain excess oil. Set aside for later use.

3. Frying the Blood Cockles

Using the same pan and remaining oil from frying the tofu, add the pre-cooked blood cockles. Cook over medium heat for approximately 2-3 minutes, stirring gently to crisp their shells slightly and enhance their flavor. The goal is to achieve a slight crispness on the outside while maintaining the tender, briny interior.

Once done, transfer the cockles to a plate lined with paper towels to absorb excess oil. Set aside for combining later in the stir-fry process.

4. Preparing the Spice Paste

The spice paste is the heart of this dish, providing depth, aroma, and heat. Use a mortar and pestle for authentic flavor, or a food processor if preferred for convenience.

Place the red bird’s eye chilies, garlic, shallots, shrimp paste, tomato, and a pinch of fresh turmeric into the mortar. Grind or process until you achieve a coarse, fragrant mixture—this coarse grind preserves some texture and enhances the dish’s rustic appeal. If using a food processor, pulse briefly to avoid over-processing into a smooth paste.

5. Sautéing Aromatics and Spice Paste

In a large wok or skillet, heat 2-3 tablespoons of oil over medium heat. Add the sliced garlic and shallots (the sliced ingredients), and sauté until fragrant and lightly golden, about 2-3 minutes.

Add the sliced ginger, green bird’s eye chilies, and tomato slices, stirring well. Continue to sauté until the vegetables soften, releasing their aroma, approximately 3-4 minutes.

Next, incorporate the coarse spice paste. Stir well, ensuring the paste is evenly distributed among the aromatics. Cook for about 5 minutes, stirring frequently, until the mixture darkens slightly and fragrant oils are released, indicating the spices are toasted and aromatic.

6. Incorporating Additional Flavors

Add the bay leaves, kaffir lime leaves, lemongrass stalk, turmeric leaf, and kandis acid to the pan. Stir gently to combine, allowing the herbs to release their essential oils, which will infuse the dish with bright, citrusy, and earthy notes. Continue cooking for 2-3 minutes, ensuring the flavors meld beautifully.

7. Combining Tofu and Cockles

Gently add the fried tofu cubes and blood cockles into the aromatic spice mixture. Stir carefully to coat the ingredients with the spices without breaking the tofu or damaging the cockles. Cook on medium heat for approximately 10 minutes, allowing the flavors to meld and intensify.

This step is crucial for flavor absorption. The tofu will soak up the rich, spicy broth, while the blood cockles impart their briny essence into the dish.

8. Adding Water and Simmering

Pour in 150 ml of water, which will loosen the spices slightly, creating a flavorful broth. Bring the mixture to a gentle boil, then reduce to a simmer. Cover partially if needed. Let simmer for an additional 10 minutes, allowing the flavors to deepen and the ingredients to become tender.

9. Final Seasoning and Adjustments

Taste the dish and adjust seasoning accordingly. Add salt incrementally—start with 1/2 teaspoon and increase if necessary. If using a flavor enhancer, add a pinch to boost umami. Incorporate sliced tomato at this stage for freshness and a slight tang.

Stir gently to distribute the seasonings evenly and allow the tomato to soften slightly, about 2 minutes.

10. Serving

Remove from heat once the sauce has thickened slightly and ingredients are well-infused with spices. Serve hot, accompanied by steamed jasmine rice or your preferred side dish. Garnish with additional sliced spring onions if desired for a fresh, aromatic touch. This dish is best enjoyed fresh to savor the vibrant flavors and textures.

Preparation Tips

• Cleaning Shellfish: Always soak blood cockles in salted water for at least 30 minutes to expel sand and grit. Rinse thoroughly under cold running water before cooking.
• Tofu Selection: Use firm or extra-firm tofu to prevent crumbling during frying. Fried tofu puffs are preferable for their absorptive qualities, but fresh firm tofu works well too.
• Spice Paste: Grinding the spice paste to a coarse texture preserves some bite and enhances the rustic appeal of the dish. Toasting the spices before grinding can amplify their aroma.
• Adjusting Spice Level: Bird’s eye chilies are quite hot. Reduce the number or use milder chilies if you prefer a milder flavor. Alternatively, add more chilies for extra heat.
• Flavor Infusion: The herbs and spices used, such as kaffir lime leaves and lemongrass, should be bruised or slightly crushed to release maximum aroma.
