Traveling with sourdough starter We recently got a sourdough starter, and have loved trying out many different recipes with it.

In a few weeks we will by flying home (after spending the summer in Alaska), and we would really like to take the starter home with us.

What's the best way to get it safely through the airport?
Treat it like any liquid.  You don't need much.  Just put some in a 100 ml plastic bottle if carrying on.  Alternately, if checking your bags, put your starter in a larger plastic container with a screw cap...like a Nalgene bottle, for example.  You can build it back up once you get to your destination.
