What Can You Do With Leftover Frying Oil?
When frying in oil, the question of what to do with the leftover frying oil is always a problem. It can’t be just thrown down the sink without dire consequences to the plumbing. It also can’t be thrown in the trash because of it soaking through everything and hurting the garbage process. A lot of people bag the oil and freeze it to throw away later, which works, whether in the sink or the trash. But then one has old oil in the freezer until remembering to throw it away.
The Japanese have a great product they use after frying, however. It’s called katameru tenpuru. Here’s a picture of it in the box.
It’s little crystals that you sprinkle on the pan with the oil still in it – and slightly hot. You wait a little while – less than an hour – and the whole thing is solidified. I used a spatula to take it out of the pan and simply flip it, pancake style – into the trash, where it’s completely safe.
Perhaps they have this product in other places and I just haven’t seen it. I think this is completely ingenious, and it makes frying a breeze. I don’t do a ton of frying, but the Japanese have some terrific and light recipes for a fast fry that require oil. I’ve tried a few and been frustrated afterward with the cleanup of the experience even though the food came out just great. No more frustration with this product around!
