Speak to Anan T'Mari, the asari bartender at the Vortex bar in the Nexus Docking Bay. The task is available once Vortex is opened.
You will able to find ingredients at the following locations:
- Hyperion Atrium - A small box among larger containers and first aid boxes located in a small control room between the tram entry stairs and the stairs leading to the atrium.
- Havarl - The package is about 3/4 the way down the first major bump-out going south. It is also directly south and slightly left of the forward station in the map's center. The package is in the tunnel that leads to the monolith where the angara are found in stasis.
- Kadara Badlands - In the Sulfur Springs area to the lower west, not far from a forward station. The package will be in a raider camp.
Simply return the packages to Anan to complete this quest.
