For the Mashed Potatoes
Place the potatoes in a large pot and add the salt.2 lb potatoes1 tablespoon salt
Pour in enough cold water to cover the potatoes completely.
Place the pan over high heat and bring it to a boil.
Turn the heat down to keep it at a rapid simmer and cook for 12-14 minutes until the potatoes are soft. (When you stab them with a knife, they should fall into two pieces)
Drain the potatoes well and let them sit for a few minutes so any extra moisture evaporates.
Use a potato masher or ricer to mash the potatoes.
Stir in the butter.3 tablespoon butter
Heat the cream in the microwave for 45 seconds until hot but not boiling. Add it to the mashed potato and use a wooden spoon to combine thoroughly.¼ cup cream
Check for seasoning, and then cover the pan with a lid to keep the potatoes warm.

Place a large non-stick frying pan/skillet over medium-high heat and add the oil.2 tablespoon olive oil
Once hot, add the salmon presentation side down and cook for 3 minutes until golden. Flip the salmon and cook for 2 minutes on the other side.

Notes
You want a good all-rounder that is floury and fluffy. Sebago (the dirt-covered ones, Russet, or Maris Piper are the best picks. Yukon gold gives excellent flavor, but they aren't quite as fluffy. You could use a mix of them for the best of both worlds.
You can use fresh or frozen salmon fillets for this recipe. I buy skin-off salmon as the sauce means you can't keep the skin crispy, and soggy salmon skin isn't pleasant! You want salmon fillets that are around 6oz/170g each.
Anything dry that you enjoy drinking. For me, that is usually a Sauvignon Blanc or a Viognier. If you don't consume alcohol, replace it with extra broth and ½ teaspoon of lemon juice or white wine vinegar.
You can use fish, chicken, or vegetable broth for this recipe. I always buy the low sodium/reduced salt varieties.
My standard mix is chives, dill, and parsley. But chervil, tarragon, oregano, lovage, or sorrel are all great to use (but they are harder to find in the grocery stores!)
Buy a block of parmesan and grate it yourself; you'll be amazed! Pre-grated cheese is coated to stop it from clumping, and this also prevents it from melting smoothly. So you end up with a grainy sauce.
