When you click a link labelled "world's fluffiest pancakes", do you want to read 16 boring pages of stories about someone's grandma before you get to, you know, the thing you actually clicked on?
My favorite buttermilk style pancakes are from Corner Bakery. Just hit all the right notes for me, but I can't seem to make them at home. Hot, fluffy, a little chewy. Super yummy.
At home, the Bisquick in a bottle mix is actually quite good, it's just so much batter in one bottle we rarely make it. We have another mix we use that's decent. It even better with buttermilk. My home experiments haven't been amazing enough to make them worth the bother over a pre-made mix.
...and I should shut up, this is about Louis Armstrong. I don't even know if he liked pancakes.
But back to Louis Armstrong, still on the topic of pancakes: https://greatchefs.com/recipes/tournedos-louis-armstrong/
The trick I've been using is to wait a little while after mixing the batter, so that the leavening agents have time to work.
