I have been raised on too much saleratus in the bread, and I know it.”

From Molly Brown's Post-Graduate Days by Nell Speed

It is the greatest possible quandary to be in, to be set down with flour, water, and a tin of saleratus or baking-powder, and to have to make the bread or go without.

From Two Years in Oregon by Wallis Nash

Hot milk, a little fried pork, two of the eggs, and a loaf of saleratus bread were all she had to offer, but it was very welcome to the hungry travellers.
