Russians love mayonnaise. I mean, they really love it. I have been meaning for two years to take a photo of the mayonnaise aisle (yes, mayonnaise gets its own aisle) at the hypermarket. I finally got some photos (taken surreptitiously, having already learned that they don't like you taking photos at Auchan).
They have "classic" mayonnaise, mayonnaise "Provencal," olive oil mayonnaise, quail's egg mayonnaise, Lenten (vegan) mayonnaise, chili-flavored mayonnaise, horseradish-flavored mayonnaise, light versions of all of these, and other flavors. I have never seen so much mayonnaise in one place.
