We always snap into action when our kitchen sinks get clogged, but its best way is to clean it regularly so to avoid this situation. This will also prevent unpleasant odors from happening. Pour a pot of boiling water down the drain. Add 1/2 cup of baking soda. Let this sit for a few minutes. Next, add a 1 cup mixture of lemon juice and very hot water to the drain. Cover this with a plug so the reaction will be contained below the surface. Let this sit for 5 or 10 minutes, then flush again with boiling water. Try to do this before and after your Thanksgiving dinner preparations to avoid any problems!
