I am not a big fryer but tonight I tried fried fish tacos. By the way they were delicious. Any way the recipe called for 350 degree oil. I used a thermometer and stirred the oil occasionally to mix it up. When it got to 350 I put in my fish and much to my disbelief the temperature climbed. It went up over 400 and I was scared. I thought when you added food the temp was supposed to drop. Please advise me on my foolishness as I need your advise.
