I would like to learn a couple of languages (polish and Japanese - I already learned Spanish to a decent degree) but it seems like every solution is closed source.
I would use books but listening (and speaking) are very important and books won't help with those.
What would you guys recommend?
That's fair. The salmon i do at high temp then lower immediately and broil in a marinade (soy sauce and rice wine and yuzu).
The charcoal stuff is black ginger that the salmon was cooked with.
