Why do green olives come in jars and black olives come in cans?
<|assistant|>
Green olives grow on trees and require minimal processing and preservation, while black olives are often dried and cured prior to canning, giving them a slightly different texture and flavor. The jar is best for preserving the flavor of green olives, while the can is ideal for allowing the robust flavor of black olives to come through. Additionally, green olives may contain pits which can vary in size and texture, making them more suited to jarred preservation.  Black olives on the other hand, typically do not have such variance and are thus more suited to canning.
