Got this one off triple D and Bob's son gave out the quantities, he makes it 1 gallon at a time but you could easily scale down. The recipe is on the internet but it's not quite the same as this one.
1/2 gallon of mayo
3 tbl of horse radish
3 tbl of ground black pepper
3 tbl of lemon juice
1/4 gallon of vinegar
2tbl of red pepper powder
1pt of apple juice
2 tbl of salt
