It's best to have all your ingredients prepared and everything you need, ready to go. Because once the "candy" is ready, you have to move quick. I've found the best work surface for this is a cookie sheet lined with parchment. I used sticks for my apples, but it's truly a lot easier if you use popsicle sticks (much less chance of swallowing a splinter too!). Lastly, try to choose apples that will "sit up" on their own. It will make life a lot easier.
Push your sticks into the apples where the step was.
Place your brown rice syrup into a small pot and bring to a boil. Once it bubbles, reduce heat immediately to low. Simmer for 2 minutes. Remove from heat.
When the brown rice syrup has stopped bubbling, hold one of your apples by the stick, over the pot, and spoon syrup over the apple until it has a smooth, glossing coating.
Roll in walnuts (I did this right on the cookie sheet, but you can use a separate flat surface.)
Repeat with all your apples. (Recipe can easily be doubled, tripled or quadrupled.)
Set the apple on the parchment and place the entire cookie sheet in the fridge. Chill for at least 1 hour.
