I am familarfamiliar with "Das schmeckt" to say you like the taste of something and I was working on a lesson in DuoLingo.com and used it in context a couple of times. I was looking up how to spell it, and found a few sites that mentioned "schmecken lassen" and gave "Tuck in" as the meaning. When I searched for "schmecken lassen", I mostly got more "taste" references, but a few more "tuck in" references.
How do "to taste" and "to tuck in" relate?
