Ok, it's been 2 weeks since I made the marmalade and it has thickened up quite a bit but still not really set. I am going to leave it as it is, it will be good over ice cream or a slice of pound or sponge or angel food cake. It has a nice flavor with a minimal amount of rind in it. I gave 2 - 1/2 pint jars to friends visiting from OH to take home with them today, the guy really liked it. I will use this recipe again and I now have a candy thermometer in my possession. Thanks to all of you for your advice.
