Groundnut soup i presume is an Edo soup right? I haven't tasted it yet, would have if i had someone who cooks pretty well prepare it for me, but after reading your post, i don't think i would wish to try on again.

I have a similar habit to yours. The thing of smelling food before eating. No matter how delicious a meal looks or taste, if the smell doesn't go well with my nose am definitely not eating that food.
