I have the sauce went home prepared horseradish with beet juice. But you just need grated horseradish as the sauce must be white. So grate the horseradish to get 1/2 Cup 200 g. Pour the broth or hot boiled water.

Add to the horseradish, sugar, vinegar. Apple peel and grate on a grater with medium-sized cells. Sent to the hell.

In the end add the yogurt and thoroughly mix everything. By the way, this sauce we destroyed the burgers from the nuts. And you choose where it will be served to meat or vegetables.
