Yesterday, I made hot pepper jelly. The recipe called for 1.5 pounds red bell pepper, 12 ounces red jalapeños, seeded, 3 3/4 cups sugar, 1 1/2 cups white wine vinegar, and 9 tablespoons liquid pectin. When the jelly was almost done, I added the pectin, boiled it hard for one minute, as instructed, and put it in jars. I used a water bath method. All jars sealed, but the jelly turned out very thin--like a syrup. Almost as if I'd added no pectin at all. Any ideas as to why this happened?
You deserve a cookie.
