Step 1: Prepare the Tofu

1. Press the Tofu:

To ensure the tofu gets crispy, start by pressing the tofu to remove excess moisture. Wrap the tofu block in a clean kitchen towel or paper towels, place a heavy object (like a skillet or a can) on top, and let it sit for about 10-15 minutes.

2. Cut and Coat the Tofu:

Once the tofu is pressed, cut it into bite-sized cubes. In a large bowl, toss the tofu cubes with 3 tablespoons of cornstarch until evenly coated. The cornstarch helps create a crispy crust when pan-fried.

Step 2: Cook the Tofu

1. Fry the Tofu:

Heat 3 tablespoons of vegetable oil (and 1 tablespoon of sesame oil if using) in a large non-stick skillet or wok over medium-high heat. Once the oil is hot, add the tofu cubes in a single layer and cook for 3-4 minutes on each side, turning occasionally, until the tofu is golden brown and crispy on all sides.

2. Remove and Drain:

Once the tofu is crispy, remove it from the skillet and place it on a paper towel-lined plate to drain excess oil. Set aside while you prepare the sauce.

Step 3: Make the Sauce

1. Sauté the Aromatics:

In the same skillet or wok, add a little more oil if needed. Add the minced ginger, garlic, and sliced onion (if using). Sauté for 1-2 minutes over medium heat until fragrant and the onions have softened slightly.

2. Prepare the Sauce:

In a small bowl, whisk together the soy sauce, dark soy sauce (if using), rice vinegar, honey (or maple syrup), and black pepper. Pour the sauce mixture into the skillet with the aromatics.

3. Simmer the Sauce:

Bring the sauce to a simmer, allowing the flavors to meld for about 2-3 minutes. If you prefer a thicker sauce, add the cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons water) and stir until the sauce thickens slightly.

Step 4: Combine the Tofu and Sauce

1. Toss the Tofu in the Sauce:

Add the crispy tofu back into the skillet with the sauce. Gently toss the tofu to coat it evenly in the sauce, letting it simmer for 2-3 minutes to absorb the flavors.

2. Finish and Garnish:

Once the tofu is well-coated and the sauce has thickened, remove from heat. Garnish with sliced green onions, sesame seeds, or cilantro for added freshness and flavor.

Step 5: Serve and Enjoy

Serve the Black Pepper Tofu over a bed of steamed rice or with stir-fried vegetables. Drizzle extra sauce over the top if desired, and add a sprinkle of chili flakes for heat if you enjoy a spicier dish.
