"The manna was like coriander seed and looked like resin." Numbers 11: 7.
The exact nature of manna remains unknown. Perhaps the simplest explanation is that it was simply a divine provision, miraculously given.

Coriander, at least the types now grown, have brown rather than white fruits.
Coriander is widely grown in the Middle East and highly valued as a spice in Arab cooking. The "seed" is also used in the United States as a ground spice.
