Lightly scrub apples with mild soap and a soft scrub brush to remove the waxy coating.
Hot caramel won’t stick to a wet apple, make sure the apples are dry.
Don’t get the caramel too hot, or you’ll end up with a thin layer on the apple and the rest sliding off the apple.
Scrape excess caramel off the sides of the apple before rolling in nuts. Don’t forget to scrape the bottom of the apple to.
