The Yo Hala is dipped in what before cooking?

The correct choice is French toast batter. The Yo Hala, which likely refers to a specific dish at Metro Diner, is styled similarly to a French toast preparation. Typically, French toast is made by dipping bread in a mixture that often consists of eggs, milk, and spices, which may include cinnamon or vanilla. This batter creates a delicious outer layer that crisps up when cooked, providing both texture and flavor to the dish.

While pancake batter and egg batter are commonly used for various dishes, they don't specifically refer to the traditional preparation method associated with French toast. Milk and cinnamon could be components of the batter but don't provide the full context of how the Yo Hala is prepared. Thus, French toast batter captures the essence for this particular item, making it the accurate choice.
