Head Chef
Chef John has a recipe for blue cheese dressing and someone asked him how long it would last in the fridge. He said about a week or so. So here's where I'm a little confused.
The recipe uses buttermilk, sour cream, mayonnaise, and blue cheese crumbles. These are the things I guess would go bad. But here's my thought: wouldn't the expiration time on it only be limited by the expiration date of what goes into the dressing? In other words, if the buttermilk and sour cream expired in three weeks and the mayo and blue cheese crumbles expired in a month, why, when you combine ingredients, is the expiration time less?
Using the above examples, I would expect the dressing to last at least three weeks in the fridge before going bad. Longer if the sour cream and buttermilk lasted longer.
I've seen this before on recipes. The use-by time is a couple of days or a week but each of the ingredients, taken by themselves, would last at least a couple weeks.
Am I missing something here?
