2 russet potatoes
Heat the oil in the deep fryer to 325 °F. Fry the potatoes in batches for 5 minutes, until soft but still pale. Drain on paper towels.
vegetable oil
Fry the onion in a little oil until golden brown, about 8 minutes. Add the garlic and fry for another 30 seconds, then let it cool.
1 onion, 1 clove garlic
Mix the onion and garlic with the ground beef, salt and pepper. Shape into 4 patties, slightly wider than the buns, and press a shallow dimple into the middle of each.
No deep fryer? Fry in a heavy pot with at least 3 inches of oil and use a thermometer to check the temperature.No grill? Cook the bacon and burgers in a cast iron skillet over medium-high heat.
