Witch Recipes

The least amount of materials required for 1 brew is:
3 frog eggs
3 spittles
6 blue mushroom caps
6 horny mushroom caps
6 evil eye tails
6 curse eye tails

Make the frog/cat drops into egg+mushroom/bloody-wine using the mushie caps,
then make those into slimy canape and zingy kebab using the lizard tails,
then make the brew ("sharp and slimy" option).
Total of 13 conversations with the witch.

You can save more time with the wrap+steak recipe.

1 brew
= 1 wrap + 1 steak
= 3 egg-mush + 5 ligator skins + 3 wine + 2 croco skins

Not only can you get the ingredients faster, it takes 4 fewer conversions than the canape+kebab recipe.
