best recipe for ashen dust?

[bong water]

Depending on the tier of resources that you use to brew the Ashen Dust, you can get more of it at a time. If you brew Ashen Dust using tier 5 resources (Glowflies, Shiny Scales and Aether Bulbs), you should get a little over 100 at a time. Do it with tier 6 resources from The Cathedral, and you should get over 200 at a time.

As for specific recipes, look at the combinations that create useful items, and do one of the two combinations for that tier that does not create one of these items. If you have one of the correct combination, Ashen Dust should show up in the results preview.
