What kind of oil is use to make Auntie pretzels?

Auntie Anne's pretzels are actually made with vegetable oil, specifically a blend of canola and soybean oil. This oil is used for both deep frying the pretzels and for greasing the equipment to prevent sticking.

It's important to note that Auntie Anne's doesn't specify the exact ratio of canola to soybean oil in their blend.
