Thanks, Frig!
OK, here's the report. Sorry for being tardy!
Carrots: overdone as expected.
Potatoes: done fine
Juice for gravy: delish
Roast: Rich said he likes it better when I do it in the oven! I'm guessing it has something to do with putting it on the grill and getting the outer crust before baking it. Lotsa flavor there!
I guess we'll try again another time. I think the next foray into slow-cookery will be chili since we don't have any in the freezer. And, Price Chopper has a sale on boneless chuck roasts: $1.99/lb!
Side note: read a bit in the boston Globe magazine where they discussed stew meat vs. cutting up your own chuck. The chef/author suggested the latter since the cubes sold as "stew beef" in the markets, according to butchers he or she spoke with, originate as ends from various cuts of beef. That means different flavors and textures. He or she (sex was unidentified)said that they cut up a chuck roast for their stew meat to get more uniform texture and the best flavor. I'm sure some of us have been doing that anyway!
I cut up sirlion tip strips for beef stroghanoff so I don't have to simmer the beef for a while to get it tender.
