Coffee is a matter of taste. So no one should tell you that you’re doing it wrong. Maybe it’s just a preference.
But “immediatly” is… pretty fast. I wonder if your grind is very fine or if you have very dark beans. I don’t like coffee, so I brew mine pretty cool and for 2 minutes max so I get a very cocoy drink.
If you feel like it, you may want to try different grinds and recipes. Personally I feel like it’s worth it.
I add oil, just enough to barely coat the pan, and then tap a teeny drop of tap water from my finger onto the pan. Once the drop pops (if it got touched by the oil) or simply boils away, I can start cooking.
Additionally: butter. Butter somehow doesn’t stick for whatever reason, even if the pan isn’t fully heated up yet.
