I never had trouble with the egg mini game. My kryptonite was actually the salt and pepper seasoning game. For the longest time, I thought I had to press the button as the ring got to the golden part to pass, and this led to making me "too slow" Every gosh dang time I would attempt it. Now that I've figured out the actual objective, it's a lot easier, but I still hold a grudge.
The egg cracking minigame. I tried to be delicate as possible but I apparently keep pressing too hard on the shoulder buttons. Even with the Gourmand Ring, I still have trouble with this particular minigame.
