Storage Requirements
Every ingredient you buy from the traveling merchant or order via the world map has specific ways it can be stored. You see this information in the details, bringing up the tooltip over the icon.

As you can see from this example, mutton needs to be hung from a meat hook in order to be stored properly in the larder.

When you already have what is needed but nothing happens
If you already have, say, a meathook in your storeroom but your staffer don't put your delivered ingredients into the larder check the tooltip for an ingredient on the ground outside and you see this info in tooltip for the job for that particular item.

You might be out of available space or the store room might be unreachable for the staffer (because of wayfinding, room bans, etc).
You can also use the upwards arrow in the job info to prioritize the job storing the item in larder.
