Take the eggs, milk and sour cream out of the fridge and allow them to come to room temperature. See above note as to WHY room temperature ingredients are important.This is a good time to sift your flour, baking soda and baking powder. I do this to prevent clumps and evenly distribute the powder and soda. When you don't sift it you can end up with clumps of the powder and soda which is so gross to but into. If you don't have a fine mesh sifter, you can use a whisk and stir the dry ingredients together really well. You can add the cinnamon and cloves to this process but it is not necessary. Line a standard sized muffin tin with paper liners. Then lightly spray the top with cooking spray. This will help prevent the muffin tops from sticking to the pan.
