Once or twice a year I pull out my marshmallow recipe and make up a batch to give as gifts. I am always pleasantly surprised to remember that it takes only a few ingredients and is relatively straightforward, albeit sticky. The result is so delicious and remarkably light and fluffy. If you've never tasted a homemade marshmallow you must try it. This confection is probably closer to its mid-nineteenth century French origins than the more commonly known genus that comes in a cello bag.
There are plenty of recipes available to make your own marshmallows. Some call for corn syrup, which I use, others don't. I also like to add the vanilla flavoring early on for a mellower effect. Rather than waiting to add it at the end, I add it to the pan when I dissolve the sugar and salt into the corn syrup and water.
It's just a matter of taste. Enjoy and Happy Valentine's Day!
