For venison Reubens, etc.
Less “meh” than Thousand Island.
Russian and Thousand Island have the same base, but are anchored by different high notes. The competing notes are sweet pickle relish for Thousand Island, and horseradish for Russian. For most salads I prefer Thousand Island. But for Reuben sandwiches, it is 100% Russian — no contest.
HOWEVER, though many Thousand Island offerings on the grocery shelves are great, so far I have not found a Russian dressing that competes with this super-simple recipe.
Don't be alarmed by the horseradish and hot sauce ingredients — there is not enough to bother anybody. Upping the amount of horseradish is fine if you have the right audience. But upping the hot sauce would be out of place.
Turn the diced onion into a rough paste using a mortar and pestle, or pressing with a large heavy knife sideways to mash. You don't have to get crazy with this step, a little texture is fine. Try to corral any juice.
Transfer the onion paste to a bowl and whisk in the remaining ingredients.
DO AHEAD: The dressing can be prepared ahead of time and refrigerated in an airtight container up to 2 weeks.
