What inspired me to make Caramelized Onions with Root Beer Glaze

As a young girl, I would go with my mom to the local village and shop. Our shopping trips usually entailed stopping for a treat before we went home. Often times, it was for a beverage and my choice was always A&W Root Beer!

Because it is the 100th anniversary of A&W, I felt it would be appropriate to share with you how I still bring A&W memories into my life! It is my choice of a beverage, except now when I drink it, I choose the Diet beverage since it has zero sugar! Because I love the root beer flavor so much, I will also incorporate it into my cooking!

My love for A&W Root Beer continues!

The days of shopping with Mom are far and few between anymore. I no longer live in my hometown. And, most of my shopping over the last few years has been on my own. The world has grown, and with it, so have I!

While I am at Walmart, I always grab some A&W Root Beer. Not only because I love it, but because it will bring back my memories of the days I would go to town with Mom as a young girl! I like to bring those memories home with me and create new ones with my family and friends. And, one of those ways is to incorporate the root beer flavor in my food, like I did with these Caramelized Onions with Root Beer Glaze and Root Beer Float Cupcakes!
