My instant coffee has become one big hard mass. What can you do with coffee?

Oh no! That's a bummer about your coffee! Here's what you can do with that hardened coffee:

Unfortunately, it's unlikely you'll be able to salvage it for drinking. The coffee granules have likely absorbed moisture and clumped together, making it impossible to dissolve.

However, you can still use the coffee grounds for a few things:

* Gardening: Coffee grounds are a great natural fertilizer for plants, especially acid-loving ones like blueberries and rhododendrons. They also help repel slugs and snails.

* Composting: Add coffee grounds to your compost pile to boost the nitrogen content.

* Deodorizer: Place a small amount of coffee grounds in a bowl and place it in a smelly room to absorb odors.

* Scrubbing: Coffee grounds can be used as a gentle abrasive to scrub dishes, pots, and pans.

* Skincare: Some people use coffee grounds as an exfoliant in face scrubs.

To prevent this from happening again:

* Store your coffee properly: Keep your instant coffee in an airtight container in a cool, dry place.

* Don't store it in a humid environment: Moisture is the enemy of instant coffee.

Ultimately, the best solution might be to just throw it away and buy a fresh bag.
