how small should these meatballs be ?

I am not very skilled in the kitchen to say the least, but this was a good and easy recipe everyone seemed to like over there spaghetti. Thanks for sharing!!!

Everyone in my family raved about these meatballs.... ages 2 1/2 to 82. Yummy!

@Donna: The meatballs should be a bit larger than a ping pong ball, but smaller than a tennis ball.
Whatever size you want is really what you should make.
Larger meatballs will need to cook a bit longer.

This is a very good, very simple recipe, my family loved it.
One of the nicest things about this recipe is that it encourages one to experiment.
Don't get me wrong, the recipe as given above is absolutely heavenly in both taste and simplicity, but one thing I learned from my Mother is that if you play with the ingredients, sooner or later you will discover your own personal version.
I did substitute a dark beer for the water, and added chopped onion, and garlic to the meatballs, and very small bits of red and green peppers, mainly for the color.
I used the Mozzarella in the center, but rolled the meatballs in Parmesan before placing them in the pan to create a thick crust which adds an interesting dimension as it adds another texture, and flavor which compliment the original.
My thanks to the person who posted this excellent recipe, I'm now enjoying a tall Chianti, and the warm glow of cascading compliments from my hard to please brood.
