I strongly disagree with this on the steak part and maybe the coffee too. Many people pride themselves on buying expensive ingredients and thinking they have the best steak but it actually sucks.

To get good steak you don't need USDA Prime dry-aged steak. You just need USDA choice, picked for a bit of marbling, salted the day beforehand and dried out uncovered in the fridge, then a ripping hot heat source (grill or cast iron etc) to get a good sear on the outside (reverse or not) and a thermometer to hit medium rare on the inside.

Even a modest steak made this way tastes better than a prime steakhouse steak that was doused with salt right before cooking, where you're going to get hypertension immediately yet the meat tastes weirdly unflavorful.

To extend this analogy further, consider making BBQ brisket Texas style. Brisket is a cheap cut of tough, fatty meat. The input quality matters even less there, and it's all dependent on chef skill. Same thing with sourdough bread — 4 ingredients, all outcome depends on skill.
