Creative, Safe, and Sustainable: What to do with cherry pits?

Did you know that cherry pits contain amygdalin, a compound that can convert to cyanide if the pit is crushed or chewed? This makes proper disposal and repurposing of cherry pits essential for safety, transforming a potentially toxic byproduct into useful household items instead of waste.

Quick Summary

Cherry pits can be safely repurposed for DIY heating pads, used as baking weights, or composted, though they break down slowly. Always avoid crushing or ingesting them due to potential toxicity.

Key Points

• Toxicity Warning: Cherry pits contain amygdalin, which converts to cyanide if crushed or chewed, making ingestion of broken pits dangerous.

• Heating Pads: Cleaned, dried cherry pits are excellent for making reusable, microwaveable heating and cooling pads for soothing aches.

• Baking Weights: Repurpose dried pits as pie weights for blind-baking to prevent pastry crusts from bubbling or shrinking.

• Composting: While pits are compostable, they decompose very slowly; crushing them first is recommended to speed up the process.

• Garden Mulch: Use large quantities of cleaned, dried pits as a dense and durable mulch to suppress weeds and retain soil moisture.

• Crafting: Turn cleaned and dried cherry pits into beads for jewelry or use them in mosaic art and other decorative projects.

• Avoid Ingestion: Do not consume cherry pits or use them in smoothies, as blending will crush the pits and release the toxic compound.

Understanding Cherry Pit Safety

While enjoying delicious cherries, you might wonder about the proper way to handle the leftover pits. The primary safety concern with cherry pits stems from the compound amygdalin, which is released when the pit is crushed or chewed. An intact pit swallowed whole will likely pass through the digestive system without causing harm, but crushing it exposes the inner kernel, allowing the amygdalin to be converted into hydrogen cyanide. For this reason, it is crucial to never blend cherries with the pits in a high-speed blender and to keep them away from children who might chew on them.

Repurposing Pits into DIY Projects

Instead of discarding them, cherry pits can be transformed into a variety of useful and creative products for your home. These projects are a fantastic way to minimize waste and put a natural resource to good use.

How to Make a Cherry Pit Heating Pad

This is one of the most popular and practical uses for leftover cherry pits. They hold and radiate heat exceptionally well, making them a natural alternative to traditional heating pads.

Here’s a simple step-by-step guide:

1. Collect and Clean: Gather a sufficient amount of cherry pits. Rinse them thoroughly in a colander under running water to remove all fruit residue. For an extra-thorough clean, you can boil them for about 5 minutes with a tablespoon of baking soda.
2. Dry Completely: Spread the cleaned pits on a baking sheet or a clean towel in a well-ventilated area. They must be completely dry before use to prevent mold. Leaving them in the sun for 24-48 hours is ideal.
3. Prepare a Pouch: Sew a pouch from a durable, natural fabric like cotton or muslin. Leave one side open for filling.
4. Fill and Sew: Fill the pouch about two-thirds full with the dried pits, then sew the opening closed securely.
5. Use: Heat the pad in a microwave for 1-2 minutes for soothing warmth, or place it in the freezer for 30-60 minutes for a cold compress.

Using Pits as Baking Weights

For avid bakers, especially those who love blind-baking pie crusts, cherry pits can replace expensive ceramic or stainless steel baking weights.

• Preparation: Clean and dry the pits as you would for a heating pad. Ensure they are completely free of any fruit residue.
• Usage: Line your pie crust with parchment paper and fill it with the pits. Bake as required to prevent the crust from puffing up.
• Storage: Once cooled, store the pits in a jar or bag for future use. They are reusable for many baking projects.

Disposing and Gardening with Cherry Pits

If DIY projects aren’t your style, you can still find sustainable ways to dispose of your pits.

Composting Cherry Pits

Cherry pits are compostable, but their hard shell means they take a very long time to break down—potentially months or even years.

• Acceleration: To speed up decomposition, you can crack or crush the pits before adding them to your pile. This exposes the inner material to microorganisms.
• Patience: If you choose not to crush them, be prepared to screen your finished compost to remove the whole pits, which can then be added back to the next batch.
• Balance: Remember to balance the carbon-rich (brown) pits with nitrogen-rich (green) materials like food scraps for optimal composting.

Mulch and Landscaping

In larger quantities, cherry pits can be used as a dense, wind-resistant garden mulch.

• Application: Spread them around the base of plants to help retain moisture, keep soil cool, and suppress weed growth. Unlike some other mulches, they do not acidify the soil.
• Pest Deterrent: Some sources suggest that crushed pits may act as a natural pest deterrent due to the slight hydrogen cyanide release, which can repel snails and slugs.

Culinary and Crafting Considerations

Beyond household basics, there are more adventurous uses for pits, though extra caution is necessary for any culinary application.

Warning on Culinary Use

Recipes like cherry pit syrup or liqueur exist, but they are not a home project for the inexperienced due to the inherent toxicity of the pits. The process of creating safe infusions involves specific heating or distillation methods that neutralize the toxins. It is generally advised to stick to the safer applications listed here and avoid experimenting with homemade versions unless you are an expert.

Crafting Projects

Dried and cleaned cherry pits can be used for various crafts.

• Make unique jewelry by drilling small holes through the pits to create natural beads.
• Glue them onto surfaces to create mosaic art or decorative magnets.
• Fill small sachets with the pits for natural potpourri.
