Lots of types of tofu (think pronounce dofu)
Love tofu skin, have a decent broth, used to add protein to ‘dirty’ noodles (insta noodles.) 🍜
Amazon has it as, ‘ Vegetarian Gluten Balls ’ but tofu balls also good for hot pot 🍲 (photo attached)
Like folk said above, marinade in some sugar, little salt, some vinegar, some soy sauce, ginger, garlic, sesame oil etc. for an hour or two then cook.
I tend to keep the pickled ginger and crushed garlic pre-prepared in jars in the fridge as it’s less of a faff, faster and more convenient.
If you have a rice cooker, then cook the marinated tofu, on the top shelf, as the rice cooks.
(We tend to fry an egg over-easy on the rice too (homage to nasi goreng.))
