My first time and I couldn't be more proud. The only time I have ever made anything jam or jelly like was 3 years ago when I made pepper jelly. That almost feels like cheating because then I used packaged pectin. This time I used a recipe with just oranges, lemons, sugar and water and it came out great! I don't have a candy thermometer, so I couldn't check temperature, but I did a chilled plate test and that worked great. The marmalade set up perfectly! Within 30 seconds of removing the jars from the water bath I heard the lovely popping sound of a successful vacuum seal! It tastes really good, too. It is sweet, but really flavorful and I didn't scorch it at all while cooking. HOORAY!
