Why do green olives come in jars and black olives come in cans?
<|assistant|>
Green olives typically need to be cured before they are ready to eat, which is a time-consuming process. To facilitate this process, they are often put in a jar and sealed to preserve the atmosphere and slow the fermentation. On the other hand, black olives are often picked before they are fully ripe and require minimal curing. Because of this, they are better suited to the salting and brining process used in canning and thus are usually packaged in cans instead of jars.
