A recipe for the perfect ring-shaped snack, soft enough inside, with a crispy crust and a fine sprinkling of sugar, has been discovered — by a mathematician.
Dr. Eugenia Cheng found that a ring doughnut with an 11 millimeter hole has the best “squidgy to crispy” ratio of 3.5 to 1, and a 5.8 gram dusting of sugar will add the right amount of taste, MailOnline reports.
Cheng, who was commissioned by Domino’s Pizza to come up with the perfect doughnut, calculated that its diameter should be between 72 mm and 82 mm.
The bigger the hole, the crispier the crust, and the smaller the hole, the softer the inside.
Since doughnut shops don’t seem to survive too long in Hong Kong, maybe you could whip up some tasty ones in your kitchen to Cheng’s specifications.
Don’t forget your ruler.
