Russian mayonnaise (which they call French) is also a little spicy. Irina notes it "has a somewhat bolder flavor than American mayonnaise" and that "it is also thinner, with a consistency that is similar to cake batter."

I have no idea if this analysis of the Russian market for mayo is truly accurate, & it appears to have been translated by a machine, but I still found this somehow interesting enough to include regarding the Russian love of mayo:

"Mayonnaise in Russia is the universal seasoning added practically everywhere – in salads, soups and the second dishes, at preparation of sandwiches and sauces. Overwhelming number of Russians (about 90%) use mayonnaise at preparation of food [and] consume this product practically each day. On the average consumption of mayonnaise in Russia is [2.5 kg per person per year]. The Russian market of mayonnaise is one of the largest in the world."
