A detailed explanation of the recipe for white sauce potatoes: 1. Chop the bacon; wash the potatoes, peel and cut them into chunks; remove the tough threads from the sugar peas and blanch them in boiling water, set aside. 2. Take a frying pan, heat it up, add butter to sauté the chopped onion and bacon bits. Then add the potato chunks from step 1 and fry until golden brown. Add water (covering about half of the ingredients) and cook until mushy. Just before removing from the heat, add fresh cream, salt, and sugar peas, mix well and it's ready.
