I had Covid a couple of years ago and lost my sense of smell, naturally that effected the taste of food. I also went through a stage of parosmia as things progressed and the smells I got were awful, things I normally love to smell like coffee brewing and certain food aromas were all putrefying and disgusting.

Thankfully that part eventually passed. However, my smell has never returned back to normal...

Occasionally I'll get a true whiff of something like fresh cut grass, a fireplace or the lovely scent of lavender or such, but other than that, nada. It'll be two years next month, I miss it, and the impact it has had on my ability to taste things has deeply diminished along with it as well.
