In the small town I used to live in the local pub had a prime rib dinner. Buffet style. As we were in line dishing up are plates a Mexican guy ( east LA not south of the border) Joe came to the horseradish and asked what it was. Another friend told him and said you know hot. Joe said “I like hot”. He damn near choked when he tried it. Totally different hot. Not even hot if you don’t let any of the fumes in your sinuses. It was pretty funny though.
Yeah horseradish can be bad, too, but I love a little bit of it. I use it in shrimp cocktail sauce and am going to try some mixed with mayo for on beef sandwiches.
