UrBC, Yekaterinburg, August 7, 2015. The food embargo has meant Yekaterinburg restaurateurs are faced with shortage of good quality butter for making their pastries.

For one, Andrei Semenov, the owner of Podsolnukhi, a cafe specializing in pies, was unable to find a single good quality Russian butter brand.

'Our bakers have tried EVERY SINGLE brand of Russian 82% butter, and none are good enough. I believe the ingredients our honorable dairy manufacturers use are not the ones that the packaging claims there are there,' Semenov posted in his social network account.

'It says 'butter' on the packaging but once you start cooking, the product goes all brittle and gives off water; the thing actually tastes like a vegetable spread,' says Irina Platonova, Deputy Director of Manolo Pryanik Sweet-shop.

Restaurateurs explain that the quality of their produce has to be maintained with use of imported butter.

The National Milk Manufacturers Union had actually predicted earlier that the amount of adulterated butter and cheese items would soar soon.
