It's very delicious. However, it's somehow scary to find out that flour and butter sugar are equal to 1:1:1. It's kind of weird to say no butter, no sugar, no oil while eating bread, but everyone wants to eat it healthy, less steamed, and more deliciously. Especially for my family. Grapefruit poundcake sugar was drastically reduced and oil (canola oil) was drastically reduced in the butter, It's a recipe that comes out unexpectedly well. You'll see if you actually make it. Grapefruit pound cake that is so easy and fast, but tastes fresh and luxurious. It's heavier than castella, so it's perfect for gifts. If you think about health and dieting, you can't eat a normal pound cake, I recommend a grapefruit pound cake recipe with half the oil or sugar. Today is grapefruit, but I think you can add citrus and citrus fruits that you like.
