Step 1
Heat the neutral oil in a large pot over medium heat. Add the minced garlic and sliced ginger, sautéing until fragrant, about 1 minute.

Step 2
Add the chopped tomatoes and cook for 4-5 minutes, stirring occasionally, until they break down into a thick sauce.

Step 3
Stir in the tomato paste, light soy sauce, sugar, salt, and white pepper. Cook for another 2 minutes to deepen the flavours.

Step 4
Pour in the vegetable broth or water and bring the mixture to a boil. Reduce the heat and let it simmer for 15 minutes to allow the flavours to meld.

Step 5
Add the rice vinegar and sesame oil, stirring well. Adjust seasoning if needed.

Step 6
Prepare the hotpot ingredients by arranging the tofu, vegetables, and noodles on a platter.

Step 7
Transfer the broth to a hotpot or large serving bowl. Serve with the prepared ingredients and dipping sauces. Let guests cook their selections in the simmering broth and enjoy!
