Any use for fallen blossoms?

[Olivier]

I was wondering if there was any use for fallen blossoms on citrus trees. Can those flowers be used to make products such as orange blossom water or perfumes?

Does any of you use those flowers, and if so, how do you use them?

You can use them to add fragrance to a tea.

I believe in Vietnam pomelo blossoms were traditionally used to make a perfume or to scent women's hair.
