In ancient times in the Russian Empire, the phrase "Filippov's buns" was a symbol of high quality, and Ivan Maksimovich Filippov himself was considered one of the most famous confectioners in Moscow. He inherited the confectionery business from his father and took it to unprecedented heights. Ivan Maksimovich's first shop was located right by the bakery and produced bread in small batches. Customers were thrilled, and when asked about the secret of such amazing loaves, Filippov replied: "I have my own flour, I buy select rye so that there are no specks or dust."

By the 1840s, a network of Filippov's confectioneries already existed in Moscow. The assortment amazed with its variety and could satisfy the taste of any gourmet: kalach, vitushki, French baguettes, peklevanny bread, Rizhsky, Borodinsky, poppy seed buns, pies with various fillings, and much more. Especially popular were the buns with raisins, for which there is an interesting legend.

At that time, Filippov supplied products to the Moscow Governor-General Arseny Zakrevsky. Every morning, fresh pastries were delivered to the governor from the merchant's shops. One day, the governor found a baked cockroach in a bun. Filippov was urgently summoned for explanations. However, Ivan Maksimovich cleverly got out of the situation, claiming that it was not a cockroach but a raisin, and calmly ate the insect. The conflict was resolved, but immediately after that, Filippov hurried to the bakery, pushed the cooks aside, and grabbed a bowl of raisins, adding them to the dough. A couple of hours later, he personally delivered new buns to Zakrevsky. Subsequently, they went on sale and became one of the hallmarks of this culinary genius's network.

By the 1850s, Filippov's business reached its peak of development. Confectionery shops opened in other cities, and in 1855 he was awarded the title of Supplier to the Court of His Imperial Majesty, which was a sign of exceptional product quality. Ivan Maksimovich passed away in 1878, but his confectionery network continued to exist for several more decades.
