Every inch counts in a camper or motorhome kitchen! These handy canning jar accessories are small enough to fit in a drawer and can eliminate the need for the bigger items they’re replacing. Gather all those glass jars you have lying around and make the most of them with these 15 handy mason jar hacks.
1. Your coffee pot
A mesh pour-over cone can be used to brew coffee directly into a Mason jar, which easily doubles as a coffee mug. No filters required.

You can also use a Mason Jar to make cold brew coffee with this kit:

To keep your hands from burning when drinking hot liquids out of a jar, you can buy a sweater for your jar, or make one by knitting or crocheting, or by cutting up the sleeve of an old sweater, or, like this one, a worn-out sock.

Silicone JarJackets not only make Mason jars more comfortable to hold when hot or cold, they also protect them if dropped.

2. Cups & Glassware
Using a mason jar as a cup probably can’t be considered a mason jar hack! But if you use jars as your main drinking glasses, not only can they be used for either hot or cold liquids, they can be multi-purposed for other uses on this list.

Take your drinking glasses to go with sip-and-straw lids! These can be used with a straw for smoothies and iced beverages or sipped for hot beverages.

A specialty bottle for fruit infusions is unnecessary with this lid:

3. A blender bottle
Use a pouring spout lid and blender ball to mix protein shakes or salad dressings. The lid of a can of dry Coffee-Mate creamer will fit as well.

4. Your blender
You may already know that a regular mouth canning jar can be screwed onto a traditional blender base. There is also an extra small blender base that’s made to be used with Mason jars! Bonus: it doesn’t take up as much room on the counter.
Product currently sold out.
5. A citrus juicer
The best part about this juicer lid is that the juice can be stored in the jar after juicing, leaving fewer dishes to be cleaned!
Product currently sold out.
6. A cocktail shaker
Impress your friends with your fancy drink mixing skills with a cocktail shaker lid set.
Product currently sold out.
7. A strainer
In addition to straining, a mesh strainer can be used for making sprouts in a canning jar.
Product currently sold out.
8. Salt and pepper containers
You’re probably thinking this doesn’t take up any less space than regular salt and pepper shakers. But do you have an extra container of salt in your pantry? If so, eliminate the need for it by purchasing salt from a bulk bin and storing it in this shaker jar. The lid rotates to allow shaking or pouring of just one or both.
Product currently sold out.
9. Vases
Of course, flowers or herbs can be put in a jar without a lid! But this gadget means a single flower or one with a flexible stem will stand straight.
Product currently sold out.
10. Lunch boxes
This dip container would also be great for keeping salad and dressing separate until lunchtime. (Psst…you can accomplish the same thing using a regular flat lid and ring with an empty fruit cup.)
Product currently sold out.
Or just use this connector, which can join two jars of any shape. Soup and salad, anyone?

11. A Zoodle Maker
Ready to add more vegetables into your diet? This Mason jar spiralizer attachment will save you space over a bulky spiralizer. Make zoodles galore!
Product currently sold out.
12. Fried egg rings
Make a perfect sausage, egg, and cheese sandwich! It’s easier than you might think to make your own fast-food-style breakfast at home. Here’s a video that shows how to do it.
13. Cookie cutters
No need to hang on to your cookie cutters for making biscuits or Christmas cookies. The rings in this photo are being used to cut pie crust for single-serving apple pies baked in mason jars (get the recipe here). Maybe you don’t need a pie pan, either!

14. A muffin tin
If you don’t make muffins or cupcakes very often or usually only make a few at a time, you can eliminate the need for a specialty pan by using jar rings and baking cups on a regular baking sheet with this idea from thekitchn.com.
(Note: If using in a toaster oven, be sure you have enough clearance for the batter to rise, and consider using foil cups to avoid risk of fire.)

15. Your cheese grater
Not only can this idea save space, you can also store the cheese in the jar after grating it.


Bonus: Match storage
Okay, this last idea doesn’t actually save any space, but it is just too nifty not to mention. I don’t know about you, but I find matches always end up falling out of the original cardboard box as it deteriorates. Instead of the side of the match box, you can also use sandpaper on the lid as long as you buy “strike anywhere” matches. Cutting a small hole in the lid lets you shake a match out without having to unscrew the lid each time.
