It can be frustrating. I have had some really good commercial sausages before, various styles, and find myself wishing I could duplicate that flavor/texture.
Even for a very experienced sausage maker, it can be next to impossible to duplicate a flavor when he/she has tasted it before.
Now think about your question and having someone make a recommendation when they have never tasted that wonderful sausage before.
Like I say, it can be frustrating.
