Place 800 g cracked rye and the salt in an ordinary pan or heat resistant plastic container
Bring the water to the boil and add it boiling hot to the cracked rye and mix. Immediately after mixing the temperature is around 66 C
Mix more, cover and place it in an insulated box or wrap the pan with a thick towel or blanket. Let the mixture sit for 7 h, after which it will be noticeable that the mixture has become pretty sticky and flavorful. Then add the rye/wheat flour mixture, mix and form a loaf. The whole mixture is now pretty sticky
Coat the loaf pan with vegetable oil and loosely dust with rolled oats or wheat germ
Transfer the loaf shaped dough to the glass loaf pan and push the dough in the form tight and make the surface flat
Cover the loaf pan with a lid or aluminum foil, but do not close hermetically. Place in the oven at 95-100 C in the presence of a bowl with water (to keep the oven moist)
After 18 h (!) take the loaf pan out and let is cool down for a few hours
Release the loaf carefully not to break it. To this purpose you can cut with a paring knife between the bread and the form, then place a cutting board on top of the form and turn it upside down. The bread will now release and positioned on the cutting board. Let it entirely cool down, loosely covered
9. After the loaf has completely cooled down, slice with a wet knife in thin, 0.16 inch (0.4 cm) slices
