Get a large glass jar with a metal lid. (This could be a jar which previously stored a sauce which you brought from the shop.) Pour the liquid fat into it after have cooked a meat meal in the oven. Put the lid back on. The fat will solidify in the jar. (Store the jar under the kitchen sink). Keep filling the jar with liquid fat until it is full and then dispose of the jar in the garbage bin. Do not throw this liquid fat down the kitchen sink because it solidifies in the pipeline and clogs it up and it is also really bad news for the environment. (The water supply will become more polluted).
