What is the abbreviation for an egg with whites cooked, yolks 85% cooked but not broken, and no brown?

The abbreviation for an egg with whites cooked, yolks 85% cooked but not broken, and no brown is OMW, which stands for "Over Medium Well." This term specifically describes the doneness of the egg, indicating that the whites are fully cooked while the yolks are mostly set but still slightly runny, aligning with the description provided. The absence of brown signifies that the egg has been cooked carefully without any browning on the surface, which is characteristic of this preparation method.

In contrast, the other options represent different styles of cooking eggs. OW/OH typically stands for "Over Well," which would indicate both the white and the yolk are fully cooked. BASTED refers to eggs that are cooked in a way where hot fat or water is spooned over the yolks to help them cook without flipping, leading to different doneness than specified. UP generally means that the eggs are cooked sunny side up, where the yolks remain completely runny and the whites are only set from the bottom. Therefore, OMW is the precise designation for the method described in the question.
