To me, modern marshmallows are inferior to the mashmallows I remember from childhood (1950's). Has the recipe changed? - or is it just a decline in my taste buds?
The decline began when the packages began to say "non dairy", but I'm not sure that mashmallows ever had dairy products in them. The "non-dairy" advertising might have been a fad, similar to the "gluten free" advertising that appears on products that never had a gluten version to begin with.
Are modern marshmallows made with egg whites? Were old time marshmallows made with sugar? - or with corn syrup?
I especially notice the inferior taste of modern marshmallows when they are roasted. Another disappointment is the way "rice krispies treats" candy turns out when made with modern marshmallows.
