How many limes or lime juice should you use?

Please provide me with more context! I need to know what you're making in order to tell you how many limes or lime juice to use.

For example, tell me:

* What recipe are you making? (e.g., guacamole, margarita, lime pie)

* What is the serving size? (e.g., 4 servings, 12 servings)

* What is the desired level of lime flavor? (e.g., mild, tangy, strong)

Once you give me this information, I can help you determine the appropriate amount of limes or lime juice.
