The Doncaster, South Yorks-born star revealed that he decided to grow Japanese horseradish, Wasabi.
However, the move left Jeremy out of pocket and with his head down in his hands after things didn’t take off.
Writing in his Sunday Times column last week, he said: “Wasabi? This was by far my biggest disaster, I noted the fact that only one chap in all of Britain was growing it and saw this as an opportunity rather than a warning that it might be impossible.
“It isn’t, if you really pay attention, round the clock, but I couldn’t do that because I had potatoes to sell and fish to save and wheat and barley and rape to grow, and Who Wants to Be a Millionaire? to host and The Grand Tour to write.”
