My husband's quest to find a recipe which produces light, fluffy (rather than solid and dense) spelt bread from a bread machine has finally paid off. He did lots of experimenting, and this one has produced consistently good results. Update: can't see how to respond to the review which found the bread heavy, so responding here. If you definitely used WHITE spelt flour, not wholewheat, then it sounds as though perhaps different bread machines get different results? :-( However, there is one other possibility. Did you use fast action dried yeast, suitable for breadmakers? Or Dried active yeast which is for hand baking? We were using the former. The other thing my husband suggested trying, if you're using the correct flour and yeast, is to try upping the amount of yeast you're using, and see if that helps. You could also try upping the amount of water slightly, but try each solution separately first :-) My husband's number one rule, stemming from his scientific background :-) Hope one of these tips work, and not that it is the bread machine themselves (ours is a Panasonic SD255)
