looking for an answer to this puzzler
Today a total stranger called me asking if I knew how to fix this problem. I don't so I am asking for advice here. This person uses an electric stove. He said that he and his wife have been baking for years. Lately his oven heats to 375 degrees when he has it set to 350 and he said that no matter what he bakes in it, even brownie mixes, come out flat. He bought new baking powder and baking soda and his baked goods are still coming out flatter than they used to. He said he has another older stove in his basement and that he used the same thermometer in that one and it was right on. My first thought was that a thermostat in his oven might be goingbad. I have a gas range and am not familiar with electric ovens but I thought that they have a thermocouple or something to help regulate the oven. He also said that while his oven is registering at 375 instead of 350 his baked goods are not burnt, they just don't rise very much. I am stumped, so if anyone who might know the answer to this puzzle would post a reply I can can call him and pass it on. Thank you.
