Varenye (Russian: варенье [vɐˈrʲenʲɪ̯ə] ⓘ, Belarusian: варэнне/варэньне/сочыва, Ukrainian: варення [ʋɐˈrɛnʲːɐ] ⓘ) is a popular whole-fruit preserve, widespread in Eastern Europe (Russia, Ukraine, Belarus), as well as the Baltic region (Lithuanian: uogienė [uə̯ˈɡʲiə̯nʲeː], Latvian: ievārījums, Estonian: moos).

The word has common etymological roots with the verbs denoting cooking, boiling, brewing, or stewing (Russian: варить, Belarusian: варыць, Ukrainian: варити).

[4] In the popular Soviet children's book A Tale About a War Secret, About the Boy Nipper-Pipper, and His Word of Honour by Arkady Gaidar the antihero Little Baddun betrays his friends for "a barrel of varenye and a basket of biscuits" (Russian: бочка варенья и корзина печенья; again, in English translation jam is used instead of varenye).

Some fruits with tough skins require cooking for many hours, while others are suitable for making "five-minute varenye" (Russian: варенье-пятиминутка, varenye-pyatiminutka).

The most popular types of varenye are made from locally available berries and fruits, such as sour cherries, strawberries, raspberries, apricots and apples.

Varenye is enjoyed as a dessert and condiment, in particular as a topping for pancakes (bliny, oladyi, syrniki), as a filling for pies (pirogi and pirozhki), dumplings (vareniki), cakes and cookies, and as a sweetener for tea.
