Quark (dairy product) then known as "syrniki". In Latvia, quark is eaten savory mixed with sour cream and scallions on rye bread or with potatoes. In desserts, quark is commonly baked into "biezpiena plātsmaize", a crusted sheet cake baked with or without raisins. A sweetened treat "biezpiena sieriņš" (small curd cheese) is made of small sweetened blocks of quark dipped in chocolate. Estonian Quark is evaluated on olfaction, vision, taste, after taste, and texture and is distributed nationally as well as to nearby regions. Although common in continental Europe, manufacturing of quark is rare in the Americas. A few dairies manufacture it, such
Quark star under sufficient pressure from the star's own gravity or the initial supernova creating it, the individual neutrons break down into their constituent quarks (up quarks and down quarks), forming what is known as quark matter. This conversion might be confined to the neutron star's center or it might transform the entire star, depending on the physical circumstances. Such a star is known as a quark star. Ordinary quark matter consisting of up and down quarks (also referred to as "u" and "d" quarks) has a very high Fermi energy compared to ordinary atomic matter and is only stable under extreme
