How many onions for 3 gal potato salad?

I can't give you a specific number of onions for 3 gallons of potato salad. Here's why:

* Taste is subjective: How much onion you like is personal! Some people love lots of onion flavor, others prefer just a hint.

* Recipe variation: Potato salad recipes can vary greatly in their onion usage. Some call for diced onions, others for thinly sliced, some even use green onions.

* Potato size and type: The amount of potato you're using will impact how much onion is needed to balance the flavors.

Here's a better approach:

1. Find a recipe: Start with a potato salad recipe you like that makes a large batch.

2. Adjust as needed: Look at the recipe's onion amount. If you're a big onion fan, increase it slightly. If you prefer less, decrease it.

3. Taste test: When you're making the salad, taste it and adjust the onion level as needed.

General rule of thumb: You'll likely need about 1-2 medium onions for 3 gallons of potato salad, but adjust to your taste!
