Tarta Imperial Rusa

Description
Russian Imperial torte. This nutty, sugary treat was always served to the czars and czarinas of Russia. Made of fine ingredients — the best cognac, almonds, lovely premium butter, fresh eggs and sugar — it was a virtually unrivaled indulgence to be had at the end of every meal, and perhaps even during the meal. It was called the Russian Imperial Torte or, when it got to Spain, Tarta Imperial Rusa.
