How does greese get in a potato?

Grease doesn't naturally get inside a potato. It's usually added through cooking methods like:

* Frying: When potatoes are fried, the hot oil penetrates the surface and sometimes into the interior, especially if the potato is cut into smaller pieces.

* Roasting with fatty ingredients: Roasting potatoes with butter, bacon fat, or other fatty ingredients can allow grease to permeate the potato.

So, grease isn't inherently inside a potato; it's usually introduced through cooking processes.
