Learn how to fill, seal, and store homemade jam in the Kilner Strawberry Fruit Preserve Jar. This guide covers preparation, filling, and common mistakes to avoid.
Quick answer
The Kilner Strawberry Fruit Preserve Jar is designed for small-batch jams and preserves. Use it for storing and serving your homemade jam, following proper sterilization and sealing steps.
Why choose this jar for jam?
The Kilner Strawberry Fruit Preserve Jar holds 0.4 Litres, making it perfect for small batches or gift-sized portions. Its playful strawberry shape adds a fun touch to your pantry or table.
Because the jar is not intended for prolonged boiling or pressure canning, it is best for jams that are processed using a water bath or simply filled hot and sealed. Always check the manufacturer's guidelines for your specific method.
How to use the Kilner Strawberry Fruit Preserve Jar for jam
- 1. Sterilize the jar and lid: Wash the jar and lid in hot soapy water, then rinse. Place the jar (without the lid) in a preheated oven at 140°C (275°F) for 10 minutes, or submerge in boiling water for 10 minutes. Boil the lid separately for 5 minutes. Let them air dry on a clean towel. Do not touch the inside of the jar or lid after sterilizing; use tongs or clean gloves.
- 2. Prepare your jam: Cook your jam according to your recipe. For best results with this jar, use a small-batch recipe that yields around 400-500 ml of jam. Have the jam hot and ready just before filling. If the jam cools too much before filling, it may not create a proper vacuum seal.
- 3. Fill the jar while hot: Using a ladle or wide-mouth funnel, carefully pour the hot jam into the sterilized jar, leaving about 1 cm (1/2 inch) headspace at the top. Wipe the rim clean with a damp paper towel to remove any residue. Any jam on the rim can prevent the lid from sealing properly, leading to spoilage.
- 4. Seal immediately: Place the sterilized lid on the jar and screw it on firmly, but do not overtighten. Turn the jar upside down for 5 minutes to help create a vacuum seal, then turn it right-side up and let it cool completely at room temperature. Do not disturb the jar while it cools; moving it can break the seal.
- 5. Check the seal and store: Once the jar is cool, press the center of the lid. If it does not pop up and down, the seal is good. Label the jar with the date and store in a cool, dark place. Refrigerate after opening. If the lid flexes or pops, the seal failed—refrigerate the jam and use within a few weeks.
