Sourdough – 4ea
I searched and found out that “ea” stands for “each”. Then, regarding the example above, does it mean that this “Sourdough” menu will provide 4 sourdoughs? Or does it mean that each person will get 4 sourdoughs? I think the latter one doesn’t make sense, but I want to make sure if my understanding is correct.
You are correct that “ea” means “each” here. Most likely though this refers to a price rather than specifying a quantity of the food item.
More casual places may not explicitly use a dollar sign ($) or the word dollars with a price.
