RECIPE TIP: Make small potato cakes!
I think one of the reasons people don’t like potato pancakes like this is because they can be mushy and fall apart if you make them too big.
We make our potato cakes about 3 inches across.
Making smaller potato cakes that aren’t too thick allows them to cook more evenly. You to get the nice crunchy crisp outside layer with a creamy center layer in each bite.
