Thrasher's® has been making delicious fried potatoes since 1929. According to the recorded history of Thrasher's®, the salt and vinegar toppings harken back to the old English ways of dressing potatoes.  That fact, and the peanut oil Thrasher's® uses to fry the tasty spuds is all we will ever truly know about the “secret recipe,” started in 1929 by Mr. J.T. Thrasher, the original “Lord of the Fries.”
