Cut the 16. 0 oz (455g) of unsalted butter into 1. 0 inch (2. 5 cm) pieces to ensure smooth and even blending.
Place the room-temperature butter pieces directly into a food processor fitted with a standard metal blade.
Add the 3. 0 tbsp (1. 5 oz / 45g) of juice concentrate (or 1. 5 tbsp / 0. 75 oz / 22g marmalade/jam), the 1. 0 tbsp (0. 2 oz / 6g) of crushed cardamom seeds, and the 1. 5 tbsp (0. 75 oz / 22g) of optional orange flower or rose water to the processor bowl.
Cover the processor and blend the ingredients on high speed until the cardamom is thoroughly ground and the butter reaches a light, fluffy consistency.
Transfer the whipped mixture into decorative molds, a traditional butter crock, or an airtight container.
