Why not defrost it? Just fry it! If you ask whether the oil will splash out, it depends on how much oil you use. If there is a lot of oil, you don’t have to worry at all. You need to know that the density of water is 1.0 and that of oil is 0.8. Water sinks to the bottom and will not splash. If you plan to fry with a thin layer of oil, it probably won’t fry well
