Mussels with Beer Leeks and Cream are great flavors that blend well together. Just start with fresh mussels. Add some leeks, beer and cream and you have a delicious sauce with nice and tender mussles. So quick and easy to make in your pressure cooker or Instant pots.
Clean the mussels by scrubbing them with a brush under running water. Pull off the beard (the whiskery hairs protruding from the shell). Discard any mussels that are open, broken or don't close their shells when tapped.
Pre-heat the pressure cooker using the BROWN or SAUTE setting.
Add the butter and sauté the celery and leeks for 2 to 3 minutes. Add the beer and stir. Add the mussels and lock the lid in place.
Pressure cook on HIGH for 4 minutes.
Release the pressure using the QUICK-RELEASE method and carefully remove the lid. Transfer the mussels to a serving dish, discarding any mussels that did not open (do not force them open).
Stir in the heavy cream. Season to taste with salt and pepper. Pour the sauce over the mussels in the serving dish. Garnish with parsley and some squeezed lemon and serve with warm, crusty bread for dipping.
