And that, Bugs, is why I make salad dressings.....You can make just the amount you want to use and don't have to agonize about leftovers. I usually make enough dressing for a couple salads and then it's all used up.
Dane gets mad at me because I'm the one who tosses deli luncheon meats. He's the only one who eats the stuff and I've made it clear: if it's more than 7 days since purchase (which is on the label) it gets tossed. Period.
He had asked me to pick up some Black Forest Ham when he was working with Patrick. After a week he still had about 1/4 lb. left and I threw it away. He said, "I was going to eat that!" I just repeated what I've said and acted on for years, "It was a week old ~ it's out." I don't even discuss it anymore. Not worth the aggravation.
Remember, IF YOU SAY IT WITH CONVICTION, IT IS SO. If he says you're the food expert just BE the food expert. Tell him you threw it out because it's no good. Don't argue the point.
