Wash and cut potatoes in slices to resemble french fries. You can leave the skin on or remove it if preferred.
Place the cut potatoes in a large bowl.
Fill the bowl with cold water and ice. Refrigerate for 4 hours before frying.
When ready to cook, remove the potatoes from the refrigerator and dry them completely.
Heat a large stockpot or dutch oven over medium heat and melt the lard. Monitor the temperature of the lard, it is ready to fry at around 375℉.
Split the potatoes into two batches. Drop the first batch into the stock pot and fry for 10 minutes. Remove this batch to a paper towel lined sheet pan and fry the second batch.
After the second batch has fried for 10 minutes, remove to the paper towel lined sheet pan and return the first batch to the stock pot.
Fry the first batch AGAIN for 15-20 minutes, or until the become golden and crispy.
Remove the fries to the paper towel lined plate and salt immediately. The first batch can sit in a 100℉ oven while the second batch cooks to keep warm.
Add the second batch back into the stock pot and fry for 15-20 minutes.
Once golden and crispy, remove from the hot oil and salt immediately.
Serve right away.
