Its a meme from other parts of the world that British food is the worst too, I could give you so many reasons why too. One of my favourite jokes is that the UK invaded other countries for spices and never used them lmfao:
Whenever I travelled to other countries or try imported food, its FAR better than food here. The only times I get truly flavoursome food (by UK standards especially) is when I get organic (as most of it is processed here too) especially from farms directly naturally, I've had some amazing fry up breakfasts from bed and breakfast (BnB) places or when I go abroad.
Some restaurants work miracles here though and its usually the Asian ones from the "true" Indian ones that don't "westernise" their food and tone down the spices/chilli and add a lot of cream/milk or w/e and use jar sauces ofc. I've found Thai to be absolutely amazing here too if the restaurant is one of the truly passionate ones too and same with Indian.
In fact some Muslim guys started their own version of McDonalds here in my city, I think its just a new branch as they're all over the UK maybe but their burgers are fantastic! Proper chicken, proper meat, not these processed burgers you get. It felt like when I used to eat burgers in Kenya, hell it was so good back there, when I went back Kenya after 7 years and ate that food I love there again (from African equivalent of McDonalds/Burger King lol) I genuinely cried because of how good it tasted and how much I missed it. To this day, I still remember how I felt and how good the food was there. 3rd world country but their food was fucking amazing.
This is the food OF THE GODS for me too:
Kenyan style aloo bhajia/Maru Bhajia (Indian potato fritter things) with a spicy salsa, it was the most HOLY combination, in fact it was so holy, it went full 180 and felt unholy, like a sin to enjoy somehow! So fucking good! To this day, rarely anything competes with it for me.
