Steps for Preserving Fresh Tomatoes with Olive Oil in Large Pickle Jars
Sterilise Your Glass Jars
Wash the pickle or glass spice jars with lids in warm, soapy water and rinse properly. Then, place the glass jars in boiling water for 10 minutes, remove them, and dry them on a clean rack.
Pro Tip: Ensure these jars are heat-proof glass jars to avoid breakage or cracking due to heat.
Wash, Dry, and Prep the Tomatoes
Remove the tomato stalk, and use clean water to wash and clean the tomatoes. Dry the tomatoes using a clean towel or simply air dry them. After that, slice the tomatoes in half or simply core them to scoop the juice out of them.
Bake the Tomatoes
After scooping the juice out of the tomatoes, line the baking dish or rack with parchment paper and place the tomatoes with the sliced or cored side facing up. Sprinkle with salt and drizzle with one or two spoons of olive oil. Now, slow-bake the tomatoes for up to 2-4 hours at 50°C in the oven until they are fully dried, as desired.
Store the Baked Tomatoes in a Large Pickle Jar
Once you remove the tomatoes from the oven, allow them to cool for a few minutes. Once cool, layer the dried tomatoes in the large pickle jar or glass spice jars with lids. If you would like to add thyme or rosemary, place a few sprigs between the layers.
Pour Olive Oil into the Pickle or Glass Spice Jars with Lids
Fill the glass jars with olive oil, ensuringe all the tomatoes are fully submerged. Then, seal the jars tightly. Place the jars in your pantry away from direct sunlight.
