My wedding is coming up in two months and I'd like to make favors, and I'm thinking of jars of hot fudge sauce. There's one recipe I have that I like (though if anyone has any they love, please post it, especially if it's particularly good for storing in jars!), but I've never put the fudge sauce in jars before as gifts.
What sorts of things do I need to know? How long can fudge sauce stay good in a jar? Are there any sanitary rules I should follow? Does it matter what ingredients I use -- will certain recipes work better for storage in jars, or certain ingredients?
Any advice and ideas would be much appreciated. Thank you in advance!
