Thanks for the advice. I hear ya. It’s a cheap education and an inexpensive bass gym.

Yes, it’s a petrified kaffir lime. (https://duckduckgo.com/?q=kaffir+lime&t=iphone&ia=about) Well, almost petrified. It’s not a stone yet, but your giving me some ideas. 👀

Anyway, I had to double check my picture because I’ve created lemons like this too. Do it! To make one, leave it in your car (on a piece of paper, incase it stains/burns the surface) and then park your car in the sun for a few weeks. Just leave it in there and be normal. It dries up like potpourri ingredients.
For a while I was convinced that it helped my car smell fresher. I haven’t started a new one in a long time. That one in the image above is a few years old and comes from a time when I was using kaffir limes to flavor my Kombucha. (Yum, typing that made my mouth water.)
I usually use a lemons in the car. After it dries, they smell really really good when you scratch the skin with your finger nail. It’s good at balancing my phone while I drive and collect Partiko points, but the scratch n’ sniff part was my main motivation. It’s like aromatherapy.
I have more. I’ll show ya...

That’s my entire collection. The ones on the right are lemons and the ones on the left are kaffir limes. The lemons are easily over 5 years old. I started this little habit back in ol 2009, but I think I’ve tossed some out since then. I even cut one open to see what was inside once.
The texture is fun to look at too:

and the kaffir limes too:

Sideways pictures hmm...

Anyway, thanks for asking. Try it.
