What you need according to the original recipe
1 cup of water (to start- if you leave this on for a long period of time you'll need to add more)
1 lemon, sliced thin
2 fresh sprigs of rosemary
1 teaspoon of vanilla
Add it all to a pot and let it simmer.
After 90 minutes, we could smell it faintly, but the mixture was looking pretty bad.
However...we had something in the dehydrator overnight that was an utter recipe failure and melted the dehydrator. I decided to try this again to see if at least it could get the smell out.
I made some changes this time:
1 cup of water
1 lemon, sliced thin, HOWVER, take 2 pieces and squeeze the juice into the water before throwing those two slices in
2 fresh sprigs of rosemary, each one snapped in half
3 teaspoons of vanilla extract
I heated to a boil and then reduced to a simmer.
My whole house smells DELICIOUS.
