Making sweet potato fries
At the bar/restaurant I work at, we have tried to serve sweet potato fries. For reasons pertaining to cost, we bought our own sweet potatoes are tried to make them from scratch. But the store-bought frozen variety is muuuuuch better.
With our homemade fries, they were made the only way we know how; we slice them then pre-cook them in oil for a few minutes, let them drain, and then store them (i.e. cooler or freezer) until ready to use. But they are often soggy/gross.
How do companies that make fries (especially sweet potato fries) do it??
