As you know, on September 2020, I am taking on the challenge of offering you a new recipe every day based on a seasonal vegetable or fruit. This Caramelised Red Onion tart is one of my favorite.
I was looking for inspiration on my last visit to the market. My eyes suddenly fell on large red onions. I immediately thought that this would go very well with balsamic vinegar and maple syrup. You’ll see, the sweet and sour result really is delicious.
As for the tart crust, I thought it was the opportunity to try the Del’s cooking twist recipe “Olive Oil Whole Wheat Pie Crust”. Now based in Canada, Delscookingtwist regularly offers baking tips. I highly recommend her website which has taught me a lot.

And see you tomorrow for new inspirations!
Enjoy,
Caroline
