As a Canadian, Maple of course!

I've been going a little crazy for homemade cardamom syrup. It's a slightly citrusy spice, that has both warm and cool notes. Oddly, I really enjoy it in gin (but also in my tea lattes).

I’ve made a rosemary simple syrup a handful of times, and it does a lovely job of gussying up any old drink. Like gin, lemon, soda, with some of that is primo. I just chop up a few tablespoons, add it to 1C water and 1C sugar, and boil it for about 15 minutes, then strain out the rosemary. Easy and effective!

A friend brought me some Huckleberry lemonade mix from vacation and I went crazy for a while putting Huckleberry syrup in everything.

I use almond a lot. I also like to have pear and pineapple syrups on hand, maybe peach or apricot. I'm a Monin fan. Torani tend to have more artificial colors, faker flavors, and more preservatives.

I really love a good old fashioned with either maple syrup or brown sugar simple syrup.

Been experimenting with hot honey in a few things.

Sounds like you may like Falernum.

Check out a "corn n oil", tastes like a deluxe cola chupa chup.

Every spring I make some rhubarb syrup with rhubarb from the garden, specifically to make rhubarb sours, a spring favorite in my house. (I'll find and share the recipe link if anyone is interested.)

Ginger syrup I like, strawberry syrup, and most definitely pineapple syrup. I think pineapple I find the most useful.

Passion fruit I use the liqueur instead, the Chinola is so good.

Orgeat is great but I don't use it enough to buy it and it's hard to make a small amount. Made it from avocado pits once, that was cool.
