For me, there's not much better than an ice-cold coffee on a hot summer day. One problem though: if you want to sweeten your coffee you only have a few options. Option one is to use sugar, which is hard to dissolve and can result in a pile of sugar gunk at the bottom of your glass. Option two is using a store-bought coffee syrup, but those tend to be cloyingly sweet and flavored with junk.
The hidden third option is to make your own syrup at home. This simple caramel syrup isn't that hard and will give your coffee a beautiful rich flavor.
