Curious if you buy simple syrup or make it. I've only had it when I make it. Very easy to make. 2 parts sugar to 1 part water. (Store bought stuff has many other ingredients) Heat it up and stir to dissolve the sugar. Keeps for a long time if stored sealed in the fridge.
I mainly use simple syrup to make maple syrup by adding mapleine to it. Super easy and way better than anything you can buy aside from pure maple syrup.
I have never bought simple syrup, and have made it once. So easy to make that I can’t fathom why one would buy it. It just never gets used here so there’s not much point in trying to keep it on hand.
