Tired of feeling guilty eating fries? This could be the answer to all our prayers.

The world's No. 2 hamburger chain is launching a new crinkle-cut french fry on Tuesday that it says has about 20 percent fewer calories than its regular french fries. The chain says a small order of the new "Satisfries" clocks in at 270 calories because of a new batter that doesn't absorb as much oil. By comparison, a small order of its regular fries, sans crinkles, has 340 calories.

Burger King executives say people won't be able to tell that Satisfries are lower in calories. It says they use exactly the same ingredients as its regular fries potatoes, oil and batter. To keep kitchen operations simple, they're even made in the same fryers and cooked for the same amount of time as regular fries.

The difference, Burger King says, is that it adjusts the proportions of different ingredients for the batter to block out more oil. The company declined to be more specific. Another difference, the crinkle-cut shape, is in part so workers will be able to easily distinguish them from the regular fries when they're deep frying them together.

Still, Burger King is betting Satisfries will be so popular that people will even be willing fork over more money for them. The suggested price for a small order of Satisfries is $1.89, compared with $1.59 for regular fries. That's a 19 percent markup. Enjoy.
