Nether wart first. Then one ingredient.
A water bottle plus Nether wart is an Awkward Potion. Awkward does nothing until the second ingredient.
Fuel is blaze powder, separate from the blaze powder you brew into Strength. Three bottles fit in the stand at once.

The stand itself is a recipe card. Why you bother is in crafting and brewing.
