What I never understood was how Undyne was able to use determination when it's not something that monsters are supposed to be able to do. I also wanted to know what was up with the 'chilly pink stuff' that Alphys makes for Undyne.

What if this pink stuff is actually cryogenically frozen determination that Alphys was saving for a later experiment. After all, determination is associated with red, which is quite similar to pink; the colour could have been lightened by the frost.

Considering how the soon-to-be amalgamates took some time to wake up, enough for Alphys to conclude that the experiment failed, she was probably very generous with the amount she was giving them, so it's not unbelievable to say that an ice-cream-cone's worth of it should be okay to consume.

Anyway, this would explain why Undyne is not only able to come back as Undyne the Undying, but also why she is generally one of if not the most determined monster in the underground.
