Is the fear of tomatoes.
While I do not suffer with this exactly, I do not like them one bit and cannot abide having them in my plate, whether cooked or raw as a garnish. I have no idea why, it just is.
I can happily eat ketchup and cook with tinned diced (never whole or chunky cut) tomatoes to make a Bolagnese sauce or whatever, but that's your lot.
And I am not alone on this foible, Dave the b-i-l is just the same. How coincidental is that?
