I made variations of this recipe more than a few times. I love garlic, but do not use garlic unless you do so sparingly. Three cloves with 6 large potatoes was surprisingly off putting. This is a gorgeous sumptuous fluffy potato recipe scented of onions.
Do not use more than 3/4 cup of finely chopped greens for 6 potatoes. Some recipes say 1-1/2 cups. That makes the dish taste far too strongly of onions.
I was very surprised that the balance of flavours in this recipe was much more difficult to achieve than I thought. Follow the recipe the first time. Then improvise to suit your palate once you find what the initial recipe offers.
Key: Beat the potatoes into the cream and cheese while hot, otherwise they will be gummy. Ingredients must be combined when the potatoes are hot for a lovely fluffy mashed texture.
