Bring a pot of water to a rolling boil and blanch 100 g bean sprouts for 1 minute.
Pour the blanched bean sprouts through a strainer and shake thoroughly to remove any excess water, be careful of the hot steam and water.
Add 1 tsp Chinese-style chicken bouillon powder, 1 tsp toasted sesame oil, ⅛ tsp Japanese chili powder (shichimi togarashi), ⅛ tsp black pepper, ½ tsp sugar and 1 tsp rice vinegar to a bowl and mix until combined.
Add the beansprouts to the bowl and mix thoroughly until evenly covered.
Serve over ramen and enjoy!
Notes
Chicken bouillon powder varies by brand. My brand is 1 tsp per 200 ml, so if yours is more concentrated (e.g., 1 tsp per 300 ml or 1 cup), use touch less to avoid oversalting.
