3 Years Post Covid and Still Can Not Eat Sour Cream. Is there an alternative?

After getting Covid a few years ago, I have not been able to eat most sour cream, things that contain sour cream, and self-stable products containing some dairy ingredients. It all tastes rotten to me now.

I used to LOVE sour cream and miss it so much. The only sour cream I have been able to eat has been from Chipotle and Taco Bell. Sadly, I don’t live near either one of those places and am really craving sour cream on some Nachos.

What are some good alternatives? Or are there any easy ways to make homemade sour cream that might not tastes bad to me?
