Place 2 tablespoons of potato mixture into each lined muffin hole and press down on base and up sides to make a tart case. Bake for 1 hour until golden around edges. Cool slightly.


Meanwhile, combine half of the chives and dill in one bowl and remaining chives and parsley in another.


Spoon 1 heaped teaspoon crème fraîche into 11 rosti tart cases, then top with salmon and dill mixture. Squeeze lemon juice over. Spoon 1 heaped teaspoon tomato relish into remaining cases. Roll each prosciutto slice into a ‘rose’ and divide among relish bases. Top with parmesan and parsley mixture. Season tarts and arrange into
a Christmas tree shape. Serve.
