The following is a list of twice-baked foods.
 Twice-baked foods are foods that are baked twice in their preparation.
 Baking is a food cooking method using prolonged dry heat acting by convection, and not by thermal radiation, normally in an oven, but also in hot ashes, or on hot stones.
 When the desired temperature is reached within the heating instrument, the food is placed inside and baked for a certain amount of time.
 Such items are sometimes referred to as "baked goods," and are sold at a bakery.
The history of the Jews in the Soviet Union is inextricably linked to much earlier expansionist policies of the Tsarist Russia conquering and ruling the eastern half of the European continent already before the Bolshevik Revolution of 1917.
 "For two centuries – wrote Zvi Gitelman – millions of Jews had lived under one entity, the Russian Empire and its successor state the USSR.
 They had now come under the jurisdiction of fifteen states, some of which had never existed and others that had passed out of existence in 1939."
 Before the revolutions of 1989 which resulted in the end of communist rule in Central and Eastern Europe, a number of these now sovereign countries constituted the component republics of the Soviet Union.
The Foreign policy of the Russian Empire covers Russian foreign relations down to 1917.
 All the main decisions in the Russian Empire were made by the tsar (tsarist autocracy), so there was a uniformity of policy and a forcefulness during the long regimes of powerful leaders such as Peter the Great and Catherine the Great.
 However, there were numerous weak tsars—such as children with a regent in control—as well as numerous plots and assassinations.
 With weak tsars or rapid turnover there was unpredictability and even chaos.
Tsarist autocracy (Russian: царское самодержавие , transcr.
 "tsarskoye samoderzhaviye") refers to a form of autocracy (later absolute monarchy) specific to the Grand Duchy of Moscow, which later became Tsardom of Russia and the Russian Empire.
 In it, all power and wealth is controlled (and distributed) by the tsar.
 They had more power than constitutional monarchs, who are usually vested by law and counterbalanced by a legislative authority; they even had more authority on religious issues compared to Western monarchs.
 In Russia, it originated during the time of Ivan III (1440−1505), and was abolished after the Russian Revolution of 1917.
Zwieback is a form of rusk eaten in Scandinavia, Germany, Austria, France, Switzerland, Italy, Slovenia, Croatia, Serbia and Greece.
 It is a type of crisp, sweetened bread, made with eggs and baked twice.
 It originated in East Prussia.
 The Mennonites brought "Zwieback" to the Russian Empire; before the Russian Revolution, when many emigrated to the west, they brought "Zwieback" to Canada, the United States and other parts of the world.
Joseph Volotsky — also known as Joseph of Volotsk or Joseph of Volokolamsk (Russian: Ио́сиф Во́лоцкий ); secular name Ivan Sanin (Russian: Ива́н Са́нин ) (1439 or 1440 – September 9, 1515) — was a prominent Russian theologian and early proponent of tsarist autocracy, who led the party defending monastic landownership.
 The Russian Orthodox Church considers him a saint (along with his most notable opponent, Nil Sorsky); his memory is celebrated on 9 September and 18 October (dates in the Julian Calendar).
Tsar ( or ) (Old Church Slavonic: ц︢рь [usually written thus with a title] or цар, цaрь), also spelled csar, or czar, is a title used to designate East and South Slavic monarchs or supreme rulers of Eastern Europe.
 As a system of government in the Tsardom of Russia and the Russian Empire, it is known as Tsarist autocracy, or Tsarism.
 The term is derived from the Latin word "Caesar", which was intended to mean "Emperor" in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official (the Pope or the Ecumenical Patriarch)—but was usually considered by western Europeans to be equivalent to king, or to be somewhat in between a royal and imperial rank.
The Russian Revolution was a pair of revolutions in Russia in 1917 which dismantled the Tsarist autocracy and led to the rise of the Soviet Union.
 The Russian Empire collapsed with the abdication of Emperor Nicholas II and the old regime was replaced by a provisional government during the first revolution of February 1917 (March in the Gregorian calendar; the older Julian calendar was in use in Russia at the time).
 Alongside it arose grassroots community assemblies (called 'soviets') which contended for authority.
 In the second revolution that October, the Provisional Government was toppled and all power was given to the soviets.
Poland and Russia had exchanged diplomatic missions for centuries.
 The first ambassador in the modern meaning of this word, from Poland to Russia, was Antoni Augustyn Deboli, in late 18th century.
 After the period of partitions of Poland, in 1918, relations were established between the Second Polish Republic and Soviet Union.
 After Soviet invasion of Poland in 1939 those relations were broken, to be briefly reestablished in 1941 after the German invasion of the Soviet Union, when the Soviet Union and Polish government in exile agreed to cooperate against their common enemy, Nazi Germany.
 Those relations were broken in 1943 after discovery of the Katyn massacre.
 From that point onward, Soviet Union created its own puppet Polish government, which had its "ambassadors" in the Soviet Union.
 In 1989 the People's Republic of Poland was transformed into the modern Poland; in 1991, Soviet Union was transformed into modern Russia.
The "History of Soviet Russia and the Soviet Union" reflects a period of change for both Russia and the world.
 Though the terms "Soviet Russia" and "Soviet Union" are synonymous in everyday vocabulary, when referring to the foundations of the Soviet Union, "Soviet Russia" refers to the few years after the October Revolution of 1917, but before the creation of the Soviet Union in 1922.
