Couple questions about a counter top fryer I received for christmas. It's a calphalon fryer that holds up to 1g of oil 1. should I always use a full gallon of oil 2. is there danger of fire with these types of fryers. It is supposed to max out at 375 deg 3. is canola oil the best oil to use 4. can you reuse the oil? should it be drained through a cheese cloth after use anything else I should be aware of? Looking to use it in the next couple of weeks in prep for superbowl.
