Sophie-Claire Hoeller/Insider Idaho's Boise Fry Company is a beloved fast-food joint, where customers can choose from six kinds of potatoes and five different cuts, nine dipping sauces, and a variety of seasonings. On a visit during a trip to Boise, I ordered the russet potato as homestyle fries, gold potato curly fries, red potato po' balls, purple shoestring fries, as well as sweet potato and yam fries, and tried all the sauces. The yam fries were my favorite, closely followed by the sweet potato fries, which I enjoyed with the garlic aioli and jalapeño ranch sauces.
