Simple and refreshing for zero calories: refrigerated cucumber water. All you need is water and a few slices of peeled cucumber (if you’re trying it for the first time, use 2-3 slices to see how you like the taste).
Ok, the painful truth is that we don’t have much of a summer in Calgary. Depending on your frame of reference, 27C is hot or merely warm. Nevertheless, summer is beautiful and I’d rather pretend it’s summer and crave a cold drink on a hot summer day.
