Preheat the oven to 190°C (fan-forced).
Roll the puff pastry through the pasta roller until it is very thin.
Cut 4 to 5 strips about 4 cm wide.
Spread a thin layer of mustard, then tomato purée on each strip.
Cut the ham into strips about 4 cm long.
Place a strip of ham on the upper half of each pastry strip, letting it slightly hang over the edge.
Sprinkle with grated Gruyère cheese.
Fold the bottom part of the pastry over the filling to form a half-moon.
Roll each strip onto itself to form a rose.
Place each rose into a muffin tin.
Beat the egg and gently brush it over the roses for glazing.
Bake for 25 minutes, until golden brown.
For a vegetarian version, replace the ham with slices of grilled zucchini or eggplant. These roses can be prepared in advance and stored in the refrigerator for 2 to 3 hours before baking.
