I have been using a 90 count russet burbank for my fries. They have not held their crispiness long enough for me to deliver a crispy fry at the table. I spoke with my purveyor and they recommended I try a 60 count Idaho russet burbank. I was surprised I had to buy such a large potato to accomplish this. I was thinking of cutting them in half before putting them through our cutter. Can you confirm that a bigger potato will produce a crispier fry (with proper blanching at 325°F and re-frying at 350°F)?A:
The potato size won’t make a difference. Each potato plant has about 8-12 potatoes on it, various sizes. There are several key factors in getting a crispy fry. French fry machine temperatures, blanching/ finish frying and not overfilling baskets are some of the non-potato related things I always check first. Then there is the solids or starch content of the potato, the sugar accumulation (based on storing at temps above 40°F). The following documents might prove helpful in checking for possible issues:
