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 epoch Quark epoch In physical cosmology the Quark epoch was the period in the evolution of the early universe when the fundamental interactions of gravitation, electromagnetism, the strong interaction and the weak interaction had taken their present forms, but the temperature of the universe was still too high to allow quarks to bind together to form hadrons. The quark epoch began approximately 10 seconds after the Big Bang, when the preceding electroweak epoch ended as the electroweak interaction separated into the weak interaction and electromagnetism. During the quark epoch the universe was filled with a dense, hot quark–gluon plasma, containing quarks,
