I’ve never cooked with Lemon grass. I’m pretty sure you can, but I don’t know how. I planted a tiny bit in my garden this year because supposedly bugs don’t like it and I don’t like bugs. Well, the tiny little plant I planted is huge now! It is almost as tall as I am and just as wide. And it smells amazing! I love to go over and grab a leaf and crush it up. It smells just like lemon. Yum! I still don’t know how to cook with it, but I have a strong desire to just plant it all over my yard. It grows big and fluffy, it smells great, and if the bugs really don’t like it I’d be happy to have it!
