How long can I keep roasted red peppers? in oil? in vinegar and oil? After I roast them, I ususally drizzle with oil and refrigerate. I prefer this neutral way of storing them as I use them in a variety of ways. I usually only roast as many as I think will use up in 1-3 days. But when I buy them from my coop, I haven't as much control over the quantity. A few times I've thrown them out even though they still looked okay because I'd had them longer than 3 days and was worried about eating them. What is the best way to refrigerator store peppers and for how long? I like keeping things like peppers, olives, anchovies, etc. on hand as building blocks for quick easy meals.
