Tofu brain is a favorite breakfast food for northerners. What the landlord saw was "like soup with similar soy sauce", which was actually the result of thickening the sauce. Now I'm going to introduce a simple way to pickle tofu brain:

Put the water in a pot and bring it to a boil.

According to personal taste, choose to add the amount of soy sauce until the color of the soup is satisfactory.

Add water to the starch and make it into thin juice for later use.

Put the side dishes such as auricularia auricula slices, day lily and a little chopped green onion into a boiling pot and turn to low heat.

Slowly pour the sauce into the pot one by one, stirring constantly to make it evenly distributed. After reaching the required consistency, turn off the fire and take it out quickly.

Add coriander, Chili oil, sesame oil, etc. Add it to the marinade and the marinade of tofu will be ready.

When eating, it can be directly poured into a container filled with tofu.

I hope it helps you.
