There is a "not great, not terrible" food fight in the Russian soap opera IP Pirogova, s1e12. The two women are Elena Valyushkina and Yelena Podkaminskaya. The entire episode in on Youtube as "IP Pirogova 1 sezon 12 seriya" (in Cyrillic although you can find it via the transliteration above as well). The fight starts at 19:07.

I've searched the forum and someone already posted some messy scenes from s1e1 and s1e5, but then nothing, so this one should be new. I've also checked the rest of the show until the end of season 3, and there is nothing noteworthy there - one would perhaps expect more from a soap opera that centers around cake bakery.
