I made my first attempt at Hammelman's Olive Levain yesterday and am pleased with the result. The formula calls for mixing in the olives on the low speed in your mixer once you are done kneading but that didn't work for me. I dumped the whole mess out on the counter and worked in the olives by hand kneading. I retarted the formed loaves for about 5 hours while out for an afternoon hike then baked it up as the centerpiece for dinner. The flavor is fantastic and the olives have infused their taste througout the loaf. I think I'll be making this one again.
