Can I substitute powdered pectin for liquid?

What can be used to substitute natural pectin in orange marmalade recipe?

• Answer:

  I have made orange marmalade several times, and used no added pectin. Usually I make it with sour (Seville) oranges, but I don't think that makes a difference as I have seen seveal marmalade recipes with no mention of pectin. I do find that it often takes longer to cook the mixture down to a jelling state than the recipes often say, but it always works in the end. Hope this helps.
