So I am working on this recipe here. I have previously used this meal service, but I loved it so much I am making it again. But I don't want to pay for all the ingredients again. 

I have a small farm and have grown my own lemongrass just for this purpose. But, I have also grown my own "Sweet onions" as well. 

They look similar to this, but are not done growing. They have a larger bulb though (And on the picture of the seed bag, it showed a much larger bulb). 

So, can I use my garden onions or are these different? The tops of my onions are hollow (Not sure if that means anything).I heard that Yellow and Sweet are the same, but I thought they were not. I live in Texas, and I think it might be a kind cultivated in the area? Or not. I don't know.

Also, what exactly is a chive. I am not sure. All these onion things are confusing me.
