Do Yukon gold potatoes have a naturally butter taste?

Yukon Gold potatoes are known for their buttery flavor, but this flavor is not naturally present in the potato itself.

The "buttery" taste comes from the high sugar content in Yukon Gold potatoes. When cooked, the sugars caramelize, creating a flavor that is reminiscent of butter. This is especially true when they are roasted or fried.

So, while Yukon Golds don't have actual butter in them, the caramelization of their sugars during cooking gives them their characteristic buttery flavor.
