This is probably only a germane topic for middling cooks like myself, but what are the things that you are embarassed to admit that you fail at cooking/baking?
I feel like I have to mention that I can make char siu bao from scratch or a perfect Chicago style pizza before I can admit that I totally fail at meatballs. And - until this weekend - pancakes. And lasagna. I'm pretty sure I was always baking it uncovered the whole time, skimping on the sauce, and generally engaging in some poor assembly strategies.
Regarding pancakes, I have learned that if I do not use buttermilk and sour regular milk with white vinegar, the gluten stays sufficiently inactive and I get nice fluffy pancakes that are not inconsistent and lumpy due to my fear of overmixing them.
You'd think I'd know these things, but alas, no. I suck at pie crusts also, but I've only tried once so far, so I'll cut myself a break on that one.
I've noticed that a lot of people are really pretty terrible at the simple boneless skinless chicken breast. They're frequently undercooked and rubbery overcooked and dry as cardboard.
I also think there is one recipe that nobody could ever possibly mess up no matter how much effort was put into it, and that would be banana bread. Assuming you don't forget basic things, like, say, bananas, it is totally error proof.
