Why glass jars are your new best friend

Glass is perfect for storing dry goods, preserving seasonal produce, or giving your leftovers a second life. But if you remember sterilising jars as being a pain in the behind, read on.

Why choose glass over plastic?

• glass doesn’t leach chemicals into food or absorb smells
• it’s easy to clean, dishwasher-safe, and doesn’t stain
• jars can be reused indefinitely and are fully recyclable
• they look great on your shelves and help reduce single-use plastic

How to reuse jars (safely and easily)

• wash jars and lids in hot, soapy water and rinse well
• remove labels by soaking in warm water with a splash of vinegar or lemon oil
• for stubborn glue, use a paste of bicarb and cooking oil

How to sterilise jars

Whether you’re preserving mandarins, storing pantry staples, or making sauce, sterilising jars is essential.

Dishwasher method

• run jars through a hot cycle with no detergent
• time it so jars are still warm when filling them

Microwave method

• only use jars (no lids)
• rinse jars and leave a little water in the bottom
• heat on high for 1 minute per jar
• carefully remove using oven mitts and empty any remaining water

Boiling water method

• place jars and lids in a deep pot
• cover with water and boil for 10 minutes
• let dry upside down on a clean towel

What if the lid is rusty?

If a jar lid is rusty or dented, it’s best not to use it for preserving or food storage. Instead:

• repurpose the jar for dry goods, craft storage or vases
• look for universal replacement lids online or at homeware stores
• if the lid can’t be reused or recycled, dispose of it in general waste

Pro tips for preserving

• always fill warm jars with hot contents to prevent cracking
• leave a small gap at the top (called headspace) to allow for expansion
• seal immediately and store in a cool, dark place

Slowly does it

Make the switch one jar at a time, and you’ll be surprised how quickly your pantry (and your waste footprint) changes for the better.
