Hello Ailun,

We spray water on the surface of all the doughs such as sponge cakes, cakes, dacquoise, etc. that we bake, simply to make sure that the surface has a correct baking, as when we put the product in the oven, the surface is the one that receives the heat directly, It is simply for this reason.

I hope I have helped you

Have a nice day!
