Greenstein's Corn Bread is the ultimate Jewish rye, and it is unique in the technique with which it is made. The ingredients are the usual - rye sour, rye flour, common flour (AKA first clear flour), yeast and caraway seeds. And water. The crust is glazed with a corn starch/water mixture.
Eagleswings' struggles with a rye starter and the current interest in Jewish sour rye and corn bread have prompted me to re-post my response regarding the care and feeding of rye sour. After making sour rye breads last weekend, I took some photos of my rye sour refreshment which might be helpful to those undertaking rye bread baking for the first time.
The photos that follow illustrate the progression of each stage's ripening. The volume of the sour is, of course, increased with each stage.
