For me, nostalgic would be regular spaghetti with a kind of sauce my mom makes. I used to love it as a kid, and even today, I find it tastes delicious and also brings back memories.
One time a couple of years ago, I asked mom to make this spaghetti for my birthday dinner. But she used this spice mixture called "Herbs of Provence" instead of the old black pepper.
I still occasionally mention that incident to her when we talk about food.
