Super easy recipe to make a small jar of refrigerator tangerine preserves. I know we usually do all our preserving in the summer to have our summer harvest for winter but tangerines are mostly only in stores in winter. I love tangerines and was so happy to find this super easy recipe for tangerine marmalade. Learn To Preserve has the recipe so you can have some marmalade for your toast as soon as, well as soon as today if you want to make it today. Yumm.
