Well, suffice it to say, I had enough thickener for a good quart of gravy by the time all was said and done, but I decided to brazen it out with just 3-odd cups of milk. You can see the results here:
Note the eggshell finish, not the usual meat-juice shimmer, on the gravy. That's courtesy of flour overload, though of course I had the sense to keep cooking it until it didn't taste raw anymore. It stood up like soft whipped cream, too, rather than running lasciviously down the chicken and potatoes the way gravy's supposed to. Tasty, though. You can't beat butter, chicken fat, and crackly bits. Of course, even after I flooded the extra chicken leg with as much as seemed defensible before putting it away, I had a good cup of gravy left. I have this feeling that when it's chilled, I'll be able to slice it and eat it like aspic. Maybe on a baked potato?
Added 15 minutes later: I know what you're thinking. You're panicking and saying to yourself, Does he realize that that extra butter has cost him some of his discretionary calories?! Rest assured that I'm not about to contravene the wisdom of our bureaucratic betters and have allotted myself exactly three-eighths of a Hydrox cookie for dessert.
