Flake the meat of the smoked trout away from the skin and remove any tiny bones you see. Discard the skin and mince or chop the fish meat and set aside.
In a large bowl add your remaining ingredients (mascarpone cheese, sour cream, Worcestershire sauce, garlic powder, salt, black pepper, finely blended cane sugar, chives, parsley and lemon juice, and mix them together until fully incorporated.
Add in your chopped smoked trout and mix it once more until all pieces are well incorporated. If your dip is too thick, add in a tbsp or two of water and mix until your desired consistency is achieved.
You can serve your dip immediately, but for the best results allow your dip to rest (in a sealed container) for anywhere from 2-12 hours in the fridge for the flavors to blend together.
Store any leftovers in an airtight container for up to 5 days in the fridge or up to four months in the freezer.
