Reply To: Bracha on food you spit out?

I learned something a while ago and don’t remember which way it goes. I think that it was more important to do something that you know you need to do than do it because you’re not sure.

For example, it would be more meritorious to bracha on a food for sure than find a way around it in uncertainty.

Please correct me if I am mistaken and/or remind me of what I am talking about if you know this teaching.
