How do manufacturers measure your oven’s baking ability? It’s a piece of cake.

Your oven’s baking ability has already been tested long before it makes it to your kitchen. Appliance manufacturers put ranges and ovens through a rigorous series of tests to make sure they’re capable of churning out a steady stream of treats for you and your family.

AHAM’s ER-1 standard for household electric ranges offers a specific recipe that manufacturers use to test their baking/browning performance.
• 1 cup (185 g) hydrogenated vegetable oil shortening
• 2 teaspoons (10 cc) vanilla extract
• 2 cups (400 g) granulated sugar
• 4 eggs (192 g) (Note: Mix 4 eggs, but use only 192 g)
• 1 ½ cups (352 cc) whole milk
• 4 ½ cups (425 g) sifted soft wheat cake flour
• 4 ½ teaspoons (16 g) double-acting baking powder
• 1 teaspoon (5 g) salt

After providing a detailed mixing process, AHAM’s standard instructs testers to place four, 22 gauge aluminum 8 inch (200 mm) round cake pans, 7 5/8 inches (190 mm) in diameter (bottom) by 1 1/2 inches (40 mm) deep, each containing 0.8 lb. (363 g) of cake batter, in an oven which has been pre‐heated to 375 degrees. The cake pans’ surfaces should not be discolored to affect performance.

After 25 to 30 minutes of baking and 10 minutes of standing, and cooling to room temperature on a cake rack, the cake is judged not on the taste, but on the consistency of color across on the top and bottom of the cake.

A consistent and effective baking performance has a major impact on how your foods taste and look. Uniform heat distribution, which is measured as part of the standard, plays a critical role in your baking success.

While AHAM’s recipe may not result in the fanciest, or tastiest cake, it provides product testers with consistency in the testing process. And consistency, as any baker knows, can make or break a recipe.
