What kinds of cooking oil do restaurants use to cook french fries?!
Answers: I want to cook french fries like the big boy restaurants do. Not like Mc D's and B.K. I'm really trying to get a crisp and non greasy french fry. Does the type of potato matter? Should I buy a deep fryer?
Definitely get a Deep Fryer.
Some places use Peanut Oil, some use Lark, some use Corn Oil, some Canola Oil.
Peanut oil has the highest smoking point too. So, it can get hotter which makes the fryes get done that much faster.
I do not know what is used...but the type of potato will matter more than the type of oil. A lot of restaurants use peanut oil because it has a high burn temperature. The temp of the oil is most important so that the food fried is not overly greasy. Most foods are fried at about 350 degrees Fahrenheit, so if you don't have a deep fryer, you should at least invest in a thermometer.
peanut oil is the best for deep frying such as deep frying turkeys and can be filtered , stored and reused . I like to cut potatos like the size of steak fries and use crisco in a skillet on the stove top until brown then remove and salt immediatley to taste
You have good suggestions from the others. The only thing I can recommend is that you fry them just until lightly browned (to cook and steam the insides). Then remove from the oil and put away until ready to have them for dinner. Then put them for a second time into the oil to color them. That keeps them from getting oily tasting as well as allows them to cook all the way through without getting too dark.
I've even heard of people lightly par-boiling their potatoes to speed up the actual cooking of the spuds so they don't absorb so much oil. But you need to be sure to dry them totally after being in the water or they will spit in the oil.
The cheapest one.
