I would like to send a starter

Kayemme, I sent some freshly fed starter to my son last year. I used a plastic applesauce jar and enclosed it in 2 ziploc bags in case of leakage. Then I packed it in a box - I told the clerk what it was and she wasn't a bit concerned. It arrived safely and he still uses it. Mine only had to travel from WA to midcoast CA - you might want to send yours by some fast method. Good luck, A.

I usually dry a little starter, wrap it in plastic wrap and mail it in an envelope. No worries...

I thin a little starter to almost watery. Cover a cookie sheet with plastic wrap and spread the thinned starter VERY thinly. Place in the oven to protect from dust or whatever and let dry throroughly - it usually just takes overnight. Take it out, crumble and place in a baggie or wrap in plastic wrap.

To reconstitute, place in a small bowl and add enough lukewarm water to dissolve. This will depend on how much dried starter you are using. I would use a tablespoon or two of water to about a tablespoon of starter flakes. When dissolved, add a tablespoon or two of flour and stir in. Let set until bubbly. Add double the amount of water and flour that you added before, etc.

I've had really good luck simply overfeeding my starter so that it is much higher in flour content than I would normally store it at, putting it in a plastic container (or even double bagged zip-lok freezer bags) and send it out.  If it arrives with a week or so it will still be healthy becuase it was overfed, and can be diluted to normal consistency when it is re-fed.

I ship all of my starters in the dried stage.  I put one tablespoon of starter in a baggie and then in an envelope.  I also tape the seams, just in case.

If I send more than one, I put them in a padded envelope and also seal the seams.  I have had plain white envelopes torn in the sorting machine.  One doesn't want an unknown white powder all over the post office.

I also label the envelope just below my return address ;SOURDOUGH BREAD STARTER.

You can dry the starter and send it to them to reconstitute it. but it's easier if you just take a small amount of your starter, add some flour and knead it until you make a really firm dry dough, one that won't make a mess. Then make it into a small flat pancake, double plastic bag that, and stick it in an envelope. It will be too firm to rise much in shipping, and then when it arrives they can just disperse it into some water, then add a little flour and it will be right back the way it was in a few hours.
