When I started experimenting with syrups, I pretty quickly figured out there's a huge difference between just throwing stuff in hot water and actually infusing flavors 🌿 For vanilla or almond, you can't just boil it with sugar - you gotta let the flavors steep in the cooled syrup for a few days, otherwise you'll just end up with something that tastes flat. The basic technique is always equal parts sugar and water on the heat, but after that it's the infusion that does the magic.
For stuff like vanilla, I like to infuse the pods directly in the hot syrup once it cools down, then I strain it. With almond it's a bit trickier - you can use pure almond extract (just a little though, it's strong) or you can use crushed almonds that you let soak for 2 - 3 days in the finished syrup. The key thing is not expecting it to taste like store-bought syrup right away, you gotta give the flavors time to develop! 😊
