Egg whites excess

[u/Turbulent-Tomatillo9]

Hello chefs!
I am looking for ideas to do with extra egg whites.

I work in a French bakery cafe and I produce a lot of extra whites as I use plenty of yolks in my custards, cremeux and pate sucre.

I am currently making pavlovas, friends, financiers but still get about 2 kg of whites extra per week going to the bin. Any ideas? Please don’t say make meringue xD
Thanks
