Balsamic Cherry Tomato Caramelized Onion Conserve
This recipe takes the amazing flavor of caramelized onions with small sweet tomatoes, which we used the grape tomatoes, and infused a balsamic vinegar sauce using honey and spices.
- 2 T. olive oil
- 2 pounds sweet onions (3 large, quartered and thinly sliced)
- 1 t. sugar
- 4 cups halved cherry or grape tomatoes (measure after halving)
- 3/4 cups honey
- 1/4 cup balsamic vinegar
- 1/2 t. freshly ground black pepper
In a large skillet or enameled dutch oven add oil, onions, and sugar. Cook covered for 13 to 15 minutes on low heat, stirring occasionally until onions are tender.
Uncover and cook on medium until onions are golden brown.
Stir in the cherry tomatoes and honey to the onions. Bring to a boil over medium heat for 5 minutes or until the tomatoes are soft, stirring often until thick enough to mount on a spoon. Remove from heat add balsamic and pepper.
Filling the jars:
On a dishtowel place your hot jars and using your funnel in each jar ladle the mixture into the jars leaving 1/4” headspace. Remove air bubbles and refill to the proper headspace if necessary.
Taking a clean papertowel wet it with warm water and wipe the rims of the jars removing any food particles that would interfere with a good seal.
Using your magic wand extract the lids from the hot water and place them on the now cleaned rims. Add your rings to the tops of each of the jars and turn to seal just "finger tight".
Make sure your rack is on the bottom of the canner and place the jars in the water bath making sure that the water covers each of the jars by 1 to 2 inches. Add hot water to the canner if it doesn't measure up.
Cover the pot and turn up the heat under the canner and wait for the water to start boiling. Once the water has come to a boil start your timer for 10 minutes.
When complete turn off the heat and remove the cover and let the jars sit for another few minutes.
Remove the jars and place them back on the dishtowel in a place that they will sit overnight to cool. Do not touch or move them till the next morning.
