Cut the tofu into cubes by slicing it in a cross pattern, then divide into smaller pieces.

In a pot, add water (about two finger-widths deep) and bring to a boil over high heat. Add 1 tsp fermented shrimp, 2 tbsp red pepper flakes, and 1 tbsp sesame oil.

Add 1 tbsp soy sauce and taste the broth. If it's too bland, add 1 tsp salt to adjust the seasoning.

Add the tofu cubes to the pot. Slice 3 chili peppers and 1/2 stalk green onion, then add them along with 1 tsp minced garlic.

Let the stew boil vigorously until the tofu is cooked through and the flavors meld together.
