"Any contained item that can fit inside a refrigerator, whose quality would degrade significantly more when kept at room temperature rather than at 1-4°C, by the estimated time of use/consumption."

The term "contained" above is restrictive, and probably needs further precision. Only things that thrive inside an opaque and sealed container would fit the definition above. Otherwise, things that can affect the quality of other items (i.e., gas emanation), things that need light, things that need oxygen, things that need a specific range of moisture, things that can grow and/or move, would all need their containers to provide these conditions and/or have a dedicated location inside the refrigerator.

* Puff pastry that needs to be chilled for five minutes so that the butter doesn't melt into the flour before you do the next roll.

* Jello that needs to be set

* Sprouted beans / seeds for which you want to restrict the rate of growth

I've definitely just placed a stalk of broccoli on the bottom shelf of my fridge with no container.

[PhasmaFelis]

I would argue that the broccoli contains itself, or perhaps that the skin/surface of the broccoli is the container. (Though some people would argue that all vegetables in the fridge should at least be bagged, to prevent transfer of germs/grime.)

Does a bowl of hard-boiled eggs count as "contained"? It's not sealed.

[miguelrochefort]

Are they shelled?

[eropple]

Is the shell part of the food, or not? =)

What about activated charcoal or baking soda being used as a deodorizer? Or chilling a bottle of white wine, or pitcher of water, before drinking?

[miguelrochefort]

I thought about "things that are better consumed cold" but I forgot to include it.

Baking soda and charcoal deodorizer have been omitted because of the assumption that containers were sealed.

[Coding_Cat]

What about things still hot from the fire? You don't want to put those in the fridge either.

[ricardobeat]

Looks like you missed the point of the article. That spec is just as flawed as the other examples.

Technically, that's an answer to "what you should put in refrigerator."
