What does the term 1 piece of egg mean?

"1 piece of egg" is a bit of an ambiguous term. Here's how it could be interpreted:

* One egg: The most likely meaning, especially in culinary contexts.

* One part of an egg: This could refer to the yolk, the white, or a specific portion like a quarter of a yolk.

* One egg, broken and used: This interpretation is less common but could be used if you are talking about how much of an egg is used in a recipe, like "add one piece of egg."

To get a clearer understanding, it's best to consider the context of the phrase.

For example:

* "Add one piece of egg to the batter." This most likely means to add one whole egg.

* "This recipe uses one piece of egg yolk." This means to use only the yolk of one egg.

If you're unsure, it's always best to ask for clarification.
