A commuter-friend travelling with me to London on the train used to live in Ravensburg, in a region in Germany called Oberschwaben.
One day he told me he really misses a speciality from there called Seelen.
They are rolls with an open crumb and a slightly chewy crust, sprinkled with caraway and coarse salt.
Searching the internet I found a number of recipes, and some descriptions of the "original": a roll made with spelt, using high hydration, long fermentation, and a wet, hot bake.
The recipes I found were all nothing like the original description, so I decided to improvise, and I am very happy with the result:

Here the formula and instructions (1000g for 6 rolls):

| Processing instructions |
| Dough temperature was about 22C all the time |
| Mix Preferment, leave at room temperature for 2 hours and then refridgerate until used, best is overnight, |
| Let Preferment come back to room temperature, mix with other ingredients and work dough gently. It is very slack. |
| Let the dough rest for amout 2 hours, with 3 sets of stretch and fold during the first hour. Towards the end big bubbles should be forming. |
| Make your work surface thoroughly wet and turn out the dough onto the wetness. Prepare some baking parchament for the rolls. |
| Forming an oval with your wet hands scrape of a chunk of dough, then make a circle with your thumb and index finger, pull the dough through and put it onto the baking parchament. |
| Let it rest for another 30 minutes, |
| Sprinkle with Caraway seeds and coarse salt, |
Bake in a very hot oven with steam, ideally on a stone, mine needed 20 minutes at 230C |
