Tastes best with a high marshmallow : popcorn ratio, as shown!
Although not a traditional Lyonnais treat, this is our current favorite late night snack. Pop one bag of microwave popcorn and remove the 'old maids.' In a small saucepan melt 1 T butter, 1/4 c brown sugar, and 2-3 handfuls of marshmallows. Once completely melted and smooth, mix in 1 t vanilla. Pour the mixture of salted popcorn and stir well. Dig in!
