Khrenovina sauce is a spicy horseradish sauce served with a main course, which is very popular in Siberia. It is prepared by homogenizing fresh ingredients in a grinder: tomatoes, horseradish, garlic and salt. Ground black pepper, ground paprika, sweet bell pepper, vinegar, and sugar may also be added. This spicy horseradish sauce is sometimes also called in Russian 'khrenoder' (radish-throttler), 'gorloder' (throat-throttler), 'P.Kh.Ch.' (tomato-horseradish-garlic), 'cobra', 'flame', 'chemerges', 'vyrviglaz' (yank-out-the-eye) and 'Fantômas'. It may be served with traditional Russian meat dishes, including Russian dumplings (пельмени).
The sauce can be kept in a refrigerator for a long time without preservatives if stored in a sealed jar. Increasing the amount of horseradish and garlic used extends the length of time for which it can be stored.
