I haven't fully tested the shelf life but over time the uncovered ones may start to "melt."
In this photo you also see dipped marshmallows covered with chocolate that's mixed with shredded coconut. mmmmmm
Step 1: Follow This Recipe
Note that it has raw egg whites but when heated over 140 degrees, this becomes safe.
You should have on hand
-a very good mixer, preferably those big Kitchenaid types
-a pound of walnuts
-a pound of good quality chocolate
-a couple of trays or at least counter space
-a microwave or stove (if you need to double boil the chocolate)
Step 2: Walnut Preparation
You can grind more once you see if you need more.
Step 3: Prep the Chocolate for Dipping
The lazy girl's way of dealing with chocolate: microwave. Chop the chocolate into very small pieces with a butcher knife. Fill a bowl that will be deep enough to roll the marshmallows around.
Put about 1 cup of chocolate in the bowl and melt it for 1 minute on high.
Take it out. It probably just started melting. Stir it around for a while till it melts as much as possible. You don't want to burn the chocolate. Melt it at 30 second intervals and then stir until it is melted and smooth.
Step 4: Dip the Marshmallows
Dump the marshmallow onto the tray of walnut and roll it around. You can let it dry right there on the walnuts or transfer it to a tray covered with wax paper.
They will take a few hours to cool. It's best if the room temp is under 60. But ideal if you can do this without refrigerating.
