So I found another cool citrus at my local grocery store. This is a calamondin, or a miniature orange. It is sour, and can be a little bitter. It is supposed to be similar in sourness to a lime, but honestly I haven't been brave enough to bite into it raw. One of the produce gals at the store tried it in front of me, and her face puckered alarmingly. I want to try to preserve some in sugar syrup similarly to No-Sword Matt's recipe. I still have not been able to find any regular kumquats (although I haven't really tried that hard). I will let you know what happens with this lovely little citrus... hopefully there will not be a repeat of the cajun mandarin kumquat.
As a side note, my grocery store does carry preserved kumquats in a jar, but really where is the fun in that?
