Yes you can use essential oils for recipes. Just tried some lemongrass EO and it was delicious. Here is what I did.
-Took chicken breast and pounded it so it was even thickness.
-Placed chicken in glass pan (don't use plastic container or bag).
-Place 1 drop of essential oil on each piece of chicken.
-Add teaspoon of vegetable oil for each piece of chicken.
-Let it sit for at least 30 minutes
-Add salt
-Grill
This is great over salad or a bowl of rice.
Let me know your results.
