Yeah “gourmet” donuts have the wrong texture and usually taste funky. A beignet is what I would consider a fancy donut but mainly because lots of different toppings actually work well with them.
Sour cream donuts are the best and most places don’t even sell them anymore. “Gourmet” places don’t have them. Snowflake is the only chain that has them. So I only go to hole in the wall donut shops or Snowflake.
