Santa Muerte question

I am a new devotee and I wanted to know how to handle the offerings when I am working with another aspect of Santa Muerte. For instance, in Tracey Rollin’s book, she talks about how to give salt, eggs, and other things as offerings when working with Nina Blanca. With the green aspect, it is a different set of offerings. Do I put the white offerings to the side or discard them when it is time to work with a different aspect of Santa Muerte?
