The only doughnut that is suitable to me and the one that I like is just a plain donuts with sprinkled sugar. That's all, the reason I like it is because it is simple and a bit sweet and it doesn't give me heartburn like the other types of donuts sometimes (I do not know what is the cause of the problem).
I like old fashioned, or an egg cruller. It's odd, ones got crunchiness, the other is soft and spongy.
