Not any more! I found a write-up online (see method 2) about how to freeze herbs in an ice cube tray. Just chop up your herbs, put about a tablespoon in an ice cube tray spot and fill about half way with water. Put it in the freezer, and after it's set, fill to the top with water so the herbs are completely covered. Once completely frozen, pop out and put in a zipped baggie. When you need it, defrost it in a bowl or strainer, or just throw directly into soup or whatever might be cooking.
I also did this with a can of chipotles. Many of the recipes that call for chipotle peppers seem to only need one or two. I put one chipotle in each ice spot and a bit of sauce. I froze them completely and put those in a baggie, too.
