I have several avocado pits drying on my windowsill right now. I made a big batch of guacamole last weekend (here's my guacamole recipe if you're interested), and decided to research if the pits had any uses. I found several ways the seeds from this fruit can be used. I’m drying them for use in #4 below, but I thought I'd share all of the ideas I found while I was researching.

1. Make dye

Use both the skins and the pit to create a natural pink-hued dye for fabric. You’d think it would turn out green, but no, it turns out pink. Artist Ruth Singer offers her step-by-step technique and shows off her lovely results. The shade of pink depends on the fabric you use.

2. Save your guacamole

Keep your guacamole from going brown by putting an avocado pit in the dip. Disclaimer: This is a debatable practice. Some people swear it works. Others say it does nothing. Other anti-browning suggestions including sprinkling guacamole with lemon juice or wrapping it tightly in foil.

3. Whip up a facemask

Dry the pits, grind them up, and put them in a homemade facemask as an exfoliant. Blend a seed with your choice of ingredients: olive oil and a banana, avocado and lemon juice, or any ready-made facial scrub. The avocado seed helps the mask slough off dead skin, says Simply Jayy.

4. Eat it

You can grind up avocado pits in a smoothie. It contains several nutrients including calcium, magnesium and potassium. Blogger Elena Wilkins suggests splitting the pit with a heavy knife and cutting it up in pieces, then blending it while it's still wet. It's easier to mix and make it easier on your blender.

5. Make tea

Put chunks of avocado pit inside a tea infuser, put the infuser in a mug, and pour boiling water over it. Avocado seeds can be bitter, says EatThis, so you may need to add a little bit of honey or other sweetener.

6. Make mole sauce

Grate the pit and use it to whip up some tasty mole sauce. This recipe from Pam's Tactical Kitchen call for just 1 tablespoon and points out that the grated pit will turn orange.

7. Grow an avocado plant

Start with three toothpicks, a glass of water, some sunlight and one avocado pit, says Sustainable America. You should see the roots and stem start to sprout in just a few weeks.

8. Be creative

A chef who goes by the name of Triclaw says he goes through so many avocados in his restaurant that he felt bad tossing the seeds. He started carving them and said they were like dry clay. He's made faces, snails and all sorts of interesting shapes. Or carve the pits and make them into jewelry.

9. Wash your hair

Get clean with some homemade avocado shampoo. This easy recipe from Bread with Honey uses three dried and grated avocado pits, six cups of water and just a few ounces of your regular shampoo. The shampoo supposedly thickens and softens hair.
