Foodie Weekend - Caramelized Onion with Truffle Oil and Mozzarella Puff

Over the years my boys have developed some good relationship with the kitchen especially AB.  He would be happy to come down in the kitchen and help me stirring or chopping something while chatting away or listening to some Al-Green. One of his favorite thing to do of which he got pretty good at is caramelizing the onion. Well, I have to say it takes a lot of patience and practice to do this easy yet tedious job and my son has mastered it.  

That takes us to this simple yet yummy recipe of this week, Caramelized Onion with Truffle Oil and Mozzarella Puff.  These puffs are easy to like as they are light, very tasty, so easy and fast to make that my son could do them on his own. This recipe is perfect for last minute dish or for mom/daughter/son bonding project in the kitchen :) They make great party food too!

(makes about 15-20 puffs)

4-5 large onions, peeled and roughly sliced
A pack of 24 pieces of ready made pastry skin
1 teaspoon of balsamic vinegar
1/2 to 1 teaspoon of truffle oil 
Some salt, brown sugar and pepper
A small bag of shredded mozzarella cheese
Some extra virgin olive oil
1 egg


Caramelizing the onion
Heat some extra virgin olive oil in a pan on medium heat. 
Add onions and cook, stirring continuously until the onions are soft and translucent. 
Slightly reduce the heat,cook until the onions are well browned. 
Add a sprinkle of sugar (if desire) salt and pepper
Add balsamic vinegar and cook until onions are completely caramelized. 
Finally dribble in the truffle oil before removing pan from heat.
Set aside.

Once the onion is slightly cooled, spoon some onto a piece of pastry sheet
Be sure not to put too much or too little

Sprinkle shredded mozzarella generously
Using some water or lightly beaten eggs (in my case) seal the edges together

Using a fork, clamp the edges as seen in pic above

Arrange the puffs in a baking paper lined tray.
Brush some lightly beaten egg over 
Using the fork, make some tiny holes on top of the puffs 
(to release the pressure during baking) 
Bake in a pre-heated oven at 180 degrees for about 25 - 30 minutes or until turn golden

If you are feeling adventurous and would like to try and make your own pastry sheet, get the recipe here. Left over caramelized onion make good appetizer dipping. Add some to extra virgin olive oil and balsamic vinegar and serve with warm bread as pre-meal appetizer.

Good luck trying and have a great weekend, everybody!
