Like @Love_my_doggie, I have been a vegetarian for 30 years.
My experience is a little different though. I’m from the US, and I did not eat any fish at all, except for canned tuna, until I was 18. I also didn’t eat a lot of meat, because I didn’t like most of it.
When I was 18, one of my friends worked at our local fish and chips places. So I finally tried it, and it was good.
You have to eat it right away, directly out of the fryer, or else it will get soggy and have an unpleasant texture. It’s got to be crisp and hot, but also not dripping with grease.
The fish inside should be good, white cod, which is nice and flaky, and very neutral in flavor. Then you dip the batter coated fish in tartar sauce before taking a bite.
The “chips”, or French fries, should be made from whole, sliced russet potatoes, that are cut into big wedges. These also need to be consumed hot so they are crispy on the outside, and moist and tender on the inside, and sprinkled with salt immediately after being removed from the fryer. They’re good with ketchup, or vinegar, or both.
Good fish and chips need to be served and eaten immediately. This dish does not travel well, nor does it make good leftovers.
I too, do not have any plans to ever go off the vegetarian wagon, but if Beyond Meat wants to try to make a vegetarian version of fish and chips, I’d be happy to be one of the test marketers.
