One of my favorite PBS Space Time [0] videos discusses the nature of the matter of neutron stars, and although he doesn't discuss the different pasta types, he does discuss the theoretical possibilities of "strange" stars (where the some of the quarks flip to strange to get around the Pauli Exclusion Principle) and also some larger neutron stars may have an electro-weak core, an apple-sized core where the electromagnetic & weak nuclear forces have merged (similar to 1/1,000,000,000 after the big bang) with the mass of 2 earths.
