インスタントコーヒーは「鍋で水と粉を混ぜてから沸かして作る」と美味しい？→実際にやった人から「雑味が減る」「インスタントの生臭さが飛ぶ」などの声 - Togetter

This page summarizes Twitter discussions about brewing instant coffee. A user with coffee-related credentials claims that mixing instant coffee powder with water in a pot, then heating over low heat, produces superior taste by reducing acidity, off-flavors, and the characteristic unpleasant smell of instant coffee. The technique originated from the user's outdoor camping experience where they directly heated coffee over fire. Multiple respondents confirm trying this method and report noticeable taste improvements compared to standard preparation with hot water.
