Quick bread leavening agents include a weak base, such as baking soda (sodium bicarbonate) plus a weak acid, such as cream of tartar, lemon juice, or cultured buttermilk, to create an acid–base reaction that releases carbon dioxide. (Quick bread leavened specifically with baking soda is often called "soda bread".) Baking powder contains both an acid and a base in dry powdered form, and simply needs a liquid medium in which to react. Other alternative leavening agents are egg whites mechanically beaten to form stiff peaks, as in the case of many waffle recipes, or steam, in the case of cream puffs. Nevertheless,
Muffin dough and those that used a quick bread method, using muffin rings to shape the English muffins. Farmer indicated that stove top "baking", as is done with yeast dough, was a useful method when baking in an oven was not practical. Quickbread muffins are made with flour, sieved together with bicarbonate of soda as a raising agent. To this is added butter, eggs and any flavourings (fruit, such as blueberries, chocolate or banana; or savouries, such as cheese). The mix is turned into a pocketed muffin tray, or into individual paper moulds, and baked in an oven. The result are
