Ma’am those are baked meringues… just egg whites and sugar. The ratio is 2 oz of white sugar for each egg white. You pipe them with an open star tip and bake in a veeeery low temperature oven for a looong time. I hope is clear, otherwise, google it out… baked meringues.
I second what Regina has said. You can color them too if you want.
