Remove the risen dough from the fridge. It does not need to come to room temperature; you want to work with chilled, not soft, dough.
Roll the dough out on a well-floured silicone mat into a 45cm x 30cm rectangle, about 8mm thick.
If the dough gets too soft to handle, return it to the fridge to firm up. No mat this size? Baking paper works too, though it's a bit trickier to manage.
Slide the rolled dough onto a flat tray, return to the fridge, and let it firm up for 15-20 minutes.
Spread the room temperature cardamom filling across the dough with a silicone spatula, stopping about 5mm short of the edges on all sides.
Return the dough to the fridge to firm up again for 10-15 minutes.
Fold the rectangle in half lengthwise, edges meeting, and gently shape back into a 45cm x 15cm rectangle using the rolling pin.
Mark and cut 12 x 3.5cm strips along the long edge of the folded dough.
Cut each strip lengthwise into three, leaving about 1cm uncut at one end to hold them together.
Loosely braid the three strips and pinch the ends together.
Flip the braided strip over and loosely roll it from the pinched end back to the other end, creating the effect of a knot.
Place each knot seam-side down into a hole of the prepared muffin tins.
Transfer to your proving set up and prove until just under doubled in size, 30-40 minutes.
Meanwhile, prepare the egg wash by beating 2 egg yolks with 1-2 tablespoons cream or milk.
