Huh, I remembered that only sodium and lithium ions taste salty. Now that I tried to find a reference for that, I found https://www.chemistryviews.org/details/ezine/10125671/Correct_Answer_Salty_Taste/, which claims that potassium ions also taste salty.

I should buy some edible KCl in crystal form and add it to my salt then~
