7. Chocolate-Hazelnut Spread
It might surprise you to hear that chocolate-hazelnut spreads such as Nutella do not need to go in the refrigerator. It even says so on the label. In the cold of refrigeration temperatures, the spread actually becomes a solid and will no longer spread.
The sugar content of the spread serves as a preservative and prevents bacteria growth. Spreads like Nutella harden when refrigerated due to the high-fat content from the hazelnuts. So, if you want a smooth and creamy spread, keep it out of the fridge!
Full bulbs of garlic should be stored in a cool, dry place, such as your pantry. Keep them in a ventilated container. If you keep them in an airtight container they will mold quite rapidly. If you store your garlic properly it will stay good for months.
Once the head of the garlic clove is broken you should use all the cloves without around 10 days. Garlic is a superfood, so make sure that you keep your garlic good for as long as possible and avoid wastage.
Whole, uncut, onion bulbs should never be kept in the fridge. If you do, they will quickly become moldy and mushy from the humidity in the refrigerator. When onions are chilled the starches inside the bulb are converted to sugars.
If they are left long enough in the fridge, the onion will liquefy completely. And nobody wants that. Onions should be kept in a cool dry place in a ventilated container or easier, just keep them in the mesh bag they already come in.
