Because I like to cook, I watch a lot of cookery shows, including competitions (Masterchef, that kind of thing).
I also often get told "Oh, you should apply for one of those, you'd be great!"
Which, no. I wouldn't. I'm a very good home cook by the standards of most English blokes in their mid-forties. That's all and that's not a high bar 😂
Depending on who it is, I generally go with one of a couple of answers - if they're just looking to compliment me, I go with "Oh I'd really love to, but I wouldn't want to turn something I love into something stressful!!", or if it's someone I'm a bit more honest with, I'd say that I'm good, but I'm not *that good*.
Or, it's because I, like (I guess?) most people, have *enormous blind spots* in my cooking.
