Arrowroot powder is derived from a root plant similar to cassava. It is easily digested and is used as a thickening agent. It makes a light-textured, transulcent paste without any flavor or its own. It is used as a thickener in soups and sauces that cornstarch would make opaque. It is also less starchy. Use equal amounts as you would cornstarch. UPC: n/a
As an all-phosphate baking powder, Rumford Baking Powder does not contain any aluminum. This property makes it somewhat faster acting than typical double-acting baking powders. You’ll still see a boost of leavening in the oven, but most of the reaction occurs in the mixing bowl. While this makes a more delicate crumb structure in the finished product, do not dawdle.
