This is a wonderful marmalade recipe from Ball's 2010 Blue Book Guide to Preserving. which was their 100th anniversary edition. It adds a new twist to regular orange marmalade. The marmalade is an essential ingredient in a muffin recipe that I wanted to make, so I decided to make a batch for that purpose, and in the end I discovered the marmalade is so good with other things, too. (NOTE: The weight of the pectin might not be exact. The site would not let me list the pectin as just 1 pouch as was listed in the book. It wanted a specific weight, but my pectin pouches were not labeled for size. So I took the pectin weight from the box (that contained 2 pouces) and listed the box weight as 6 ounces.)
