Best Onion Tarts With Balsamic Onion Jam Recipes

CARAMELIZED ONION JAM WITH BALSAMIC VINEGAR

Steps:

• Fill a canning pot with water, set the lid in place, and heat on high heat until boiling. It can take awhile for the water to come to a boil, so get it started before you begin making the jam.
• Gather the jars you'll use, making sure each is clean and free of nicks in the rim, which could impede sealing.
• Bring a small pot of water to a simmer and turn off the heat. Drop the rings and lids into the water and leave them there until you're ready to screw them onto the filled jars.
• Put olive oil and onions in a large, heavy bottomed saucepan. Cook over medium-high heat stirring only occasionally; cook until golden, about 10-15 minutes.
• Add sugar and balsamic vinegar and cook until thickened and somewhat syrup-y. Add salt, pepper, and herbs.
• Proceed with canning steps or cool and transfer to an airtight container for refrigerator storage.
• Ladle hot jam into quarter-pint, half-pint, or pint sized jars, leaving 1/4" head space. A canning funnel makes this easy.
• Wipe jar rims to remove any jam that may have spilled. A clean rim is essential to a good seal.
• Set jar lids in place. Screw bands on finger tight.
• Use a jar lifter to gently submerge jars into hot water in the canning pot. Water should cover the top of the jars by an inch. The water will cool somewhat in reaction to the addition of the jars. Return the water to a simmer and then set the timer.
• Process for 10 minutes 0-1,000 feet altitude; add an additional minute for every additional 1,000 feet in elevation.
• Remove jars from water using the jar lifter and transfer to a solid, towel-covered surface. Allow to cool for 24 hours.
• Check seals. Lids should be solid and pulled down tight. (if they flex and pop, the jar didn't seal; put unsealed jars in the refrigerator and use those first).
• Remove rings and wash outsides of jars. Store in a cool, dry place.

BALSAMIC ONION TARTLETS

Steps:

• Under medium to low heat, place olive oil and onions in a skillet and cook for 3 or 4 minutes so that onions begin to soften but not brown.
• Add 1/3 cup of chicken broth to the onions and continue to cook until the liquid evaporates. This should take about 8 to 10 minutes.
• Add thyme and another 1/3 cup of broth, and cook until the liquid evaporates.
• Add the balsamic vinegar and the remaining broth, cooking until liquid evaporates. The final simmer takes about 12-15 minutes.
• The results will be soft and tender onions with a tart sauce that is slightly syrupy but not at all loose.
• To fill the Phyllo cups you can either use a pastry bag with a star tip or a teaspoon. If you are using cream cheese, allow it to soften a bit and mix with a tablesoon of milk.) Place a small amount of the yogurt or cream cheese in the shell filling about 1/3 to 1/2 way to the top. Top each with a spoonful of the onions.
• Bake the tartlets in a pre-heated 350 degree oven for 8 to 10 minutes.
• To garnish, you can pipe little rosettes of yogurt or cream cheese on top and sprinkle with a few fresh thyme leaves.
