Answer:
Always be very careful while deep-frying. You can use a normal cooking pot (one with tall sides is best). Put the oil in the pot and put it on the stove. To control the temperature, you'll probably want a thermometer (I usually use a candy thermometer). Just turn the heat up or down until you can maintain a consistant temperature. Don't fill the pot any higher than halfway so the oil doesn't bubble over when you put your food in to fry. Put the food in gently, don't drop it and make splashes (these could cause oil to fly out and catch fire). If the oil catches fire, don't panic, move the pot off the burner and let it burn itself out. NEVER PUT A LID ON THE POT, thousands are injured badly every year because they covered a pot of oil and it exploded all over them, and NEVER mix oil and water, because you could cause a fire and/or be badly injured. Water will cause the oil to leave the pot in a very energetic manner!
