Combine all the ingredients for the beet mixture in a blender: beets, horseradish, salt, powdered sugar, and spices.
Blend the mixture until it reaches a smooth and homogeneous consistency.
Line a plastic food container or a deep bowl with cling film to prepare for layering.
Pour the beetroot mixture into the lined container, smoothing it out evenly. Lay salmon flesh, skin side up, on top of the curing mixture and press it down gently.
Cover with cling film or plastic wrap and allow the salmon to cure in the refrigerator for 48 hours to develop flavor and texture.
After 48 hours, take out the cured fish, unwrap salmon, discard the beet mixture, rinse the fish thoroughly, and pat it dry with paper towels.
Thinly slice the Beetroot Cured salmon as desired and enjoy.
