Step-by-Step Guide to Sterilizing Glass Jars

First Step: Clean the Jars

Start by washing the jars and lids in hot, soapy water. Rinse thoroughly to remove any residue.

Second Step: Prepare for Sterilization

There are two main sterilization methods: boiling and dry heat.

Boiling Method

1. Fill a large pot with enough water to submerge the jars.
2. Bring the water to a rolling boil.
3. Carefully place the jars and lids into the pot. Make sure they are completely submerged.
4. Let them boil for at least 10 minutes.

Dry Heat Method

1. Preheat the oven to 160°C (320°F).
2. Place clean jars upside down on a baking sheet.
3. Sterilize for 30 minutes to ensure all bacteria are eliminated.

Third Step: Cool and Dry the Jars

After sterilization, carefully remove the jars using tongs. Let them cool on a clean kitchen towel or a drying rack. Avoid touching the insides to prevent contamination.

Common Mistakes to Avoid

Watch Out for These Pitfalls

• Not cleaning the jars thoroughly before sterilization.
• Using jars with cracks or chips.
