No need to avert your eyes...it's just the same home-made almond toffee Grandma used to make--with no chocolate.
Toffee does not have to be refrigerated and can be stored at room temperature for up to 2 months. However, for best toffee texture and freshness, store in an air-tight container in the refrigerator or freezer for up to 6 months (or longer), if you can stay out of it that long!
