Step-by-Step Guide to Sterilizing Weck Jars

In this blog post, you'll find a complete overview of methods for easily sterilizing canning jars and glass bottles so you can safely store food in them.  

Why is this important?

When food is heated to a high temperature (>65°C) for an extended period, the microorganisms that cause food spoilage are destroyed. Pathogenic bacteria are also rendered harmless. 

Method 1

Supplies

• Large cooking pot(s)
• Water

Step-by-Step Guide

1. Remove the lid and the rubber ring from the jar. 
2. Place the canning jar in the pot, cover with water, and bring to a boil. Make sure the canning jar is completely submerged. 
3. Let it cook for 15 minutes. 
4. In the meantime, wash the lid and the rubber rings. 
5. Carefully remove the jar from the water and, ideally, let it air dry. 
6. Let them cool before filling them. 

Method 2

Supplies

• Oven

Step-by-Step Guide

1. Preheat the oven to 150°C. 
2. Remove the lid and the rubber ring from the jar.
3. Place the jars on a baking sheet and bake them in the oven for 15 minutes. 
4. Be careful with the hot pots. 
5. Let them cool before filling them. 

Getting Started

Once they've cooled, you can use the jars to safely store food. Use them to store your homemade granola or a supply of pine nuts (which are delicious with this dish). This is also a crucial step if you want to makeyour own tomato passata.
