I do that all the time. Well, ok, some of the time.
One of the first times I did that was with Chez Helene's lemon and rosemary roast chicken. I still like those ingredients..
Mmm, a landscape construction teacher brought us all to his house mid day in an all day class, where his wife served us a soup that involved potatoes, cabbage, sausage, and cream. I've played on variations of that with different spices, different sausages, various herbs, half and half or no dairy, for decades. Trouble is, I like them all.
I tried making chinese shui mai, and bao with various stuffings, all after visiting chinatown..
I've made the meatloaf from 72 Market Street (now defunct, but such a good restaurant). That was a cinch, in that there was a cookbook with the recipe in it.
