What are some foods that hold a sentiment / nostalgia for you?

Fried mushrooms. I used to go stay with my grandparents on a Friday night and every Saturday morning I was there my Grandad would make a cooked breakfast. While he was cooking the rest of the food he used to fry me some mushrooms, I can remember sitting on the worktop eating them out of a little china bowl which had gold round the rim and a rose in the bottom. Battenburg reminds me of one of my Great Grandmas because she would always have it in. Vienetta, maybe this is a very child of the 90s thing but we didn't used to get fast food often so whenever we used to get a KFC with the Vienetta it used to feel extremely posh! (Absolutely daft thinking this on reflection 😂) The blue packet softmints, they're not as nostalgic for me now they're not actually blue. But my Great Grandad used to sometimes give me £1 to spend at the local market, it used to either be buy rainbow Kali and licorice to eat it with or a massive bag of blue softmints. I used to love Greggs Devon Iced Splits and Strawberry Tarts but they don't do them anymore!
