Some frugal practices cross the invisible line of self-destruction. Take moldy cheese. Or leave it. Some conventional wisdom dictates you should throw out the entire block if you spot any nastiness, while many foodies will tell you you’re OK if you amputate the moldy part. Either school of thought can be correct, depending on the cheese.
The Mayo Clinic breaks down which cheeses are OK to eat and which you should jettison.
Cheeses you should trash at the first sight of mold include any shredded variety, Brie, Cramembert, cottage cheese, cream cheese, Neufchatel and Ricotta. Note: the crazy capitalization pattern in the previous sentence is due to some cheeses being proper nouns because they’re named after locales.
Most others are presumably OK to chop and chomp, but if you’ve got serious doubts, err on the side of caution.
