The trick to good fries and chips?
"Good, hot oil," said Kathy Reeder, who owns Hempen with her husband, Jay Reeder.
You also want your potatoes to be well-rinsed and dried.
Museum volunteer Mary Poffenberger said a few potatoes harvested at the rural heritage museum have already been washed and left to dry at room temperature. A modern-day slicer will shave them down to slender chip-size discs on Spud Fest day. Volunteers will then fry the slim slices in a vat of lard heated to 400 degrees.
But before they hit the fryer, the potatoes will have to be rinsed several times to remove clinging layers of starch.
Poffenberger said volunteers have learned that if you skip the rinsing step, you'll get soggy chips.
Also, the chips must be kept thin. "You can hold it up and see through it," Poffenberger said.
A too thick chip will end up too soft.
"It will soak up all the grease," she said.
Lynn Little family and consumer sciences educator with the Washington County office of the University of Maryland Extension, offered fry-making tips for health-conscious fries.
She recommended baked fries instead of "fried fries," easing up on the condiments. Instead, opt for vinegar, Old Bay or the things you'd put on a baked potato.
"You have to be careful not to load them up with cheese and salt," Little said.
If you must fry, consider using a an oil free of trans-fats.
It helps to know something about the oil's burn point, which is the reason why olive oil would not work for a deep fryer.
Potato season runs late August through September, with new potatoes ready in July through mid-August. Gardeners said it wasn't a bad year for potatoes, but it could have been better.
"The heat was a little hard on everything," said Annette Ipsan, Master Gardener coordinator for the Washington County office of the University of Maryland Cooperative Extension.
Ipsan said vines dried up earlier, causing smaller yields and smaller potatoes, but it was business as usual for the people who were able to keep their potatoes well-watered.
For the first time ever, Spud Fest will offer a menu of homemade potato dishes, said museum volunteer Mary Poffenberger.
"Baked potatoes, potato salad, potato candy, potato pie," Poffenberger said.
The menu will also include french fries, Poffenberger said, but the fries won't be homemade.
She said they're still working out the kinks and plan to make fries from scratch for future Spud Fests.
