the white thing is called zephyr… a sweet thing popular in ex-soviet countries. on the Russian wiki it’s written that it dates back to ancient Greece…and therefore the God name. it’s mainly made out of egg white and sugar… and i read here and there that it also contains pureed apple (or other fruit) and pectin. they are not baked, just put in seashell-shaped “cups” and left to dry out. sometimes they are coated with chocolate.

and due to pectic, this thing is said to be healthy - link - health benefits of pectin

it might be somehow similar to Chocolate-coated marshmallow treats, I’ve tried the ones typical for Switzerland… indeed, somehow similar, but I prefer our version :)) The Swiss ones are more sticky…maybe less dried (?)

although the same ingredients, not similar to meringue - this one is baked and thus hard.

and not similar to the marshmallows that are popular in the US…those don’t have eggs.

p.s.: i just became a zephyr expert :))
