I teach TESOL (Teacher of English as a Second Language). You are correct with your astute punctuation deduction: anything after the comma indicates how it should finally look, be measured or end of process. When a receipe states they want one cup of carrots chopped (,) comma, then the final product will reside after the comma.
I use your example:1 cup grape tomatoes, quarteredis how they appear in the cup as a final product to then use.
However, I find half the fun of food is not using measures strictly... unless there is a process which is absolutely necessary for the final product... I "wing it."
I remember Justin Wilson the Cajun Chef... He was always saying, "...a little wine for the sauce and a little wine for the chef. A little more wine for the sauce and another glass for me, the chef."
