Turn on the oven to 175°C / 350°F (grill setting).
Cut out the flower tortillas with the flower cutter or use a small glass.
Place the tortilla cutouts into the mini muffin tin, pushing them down symmetrically.
Brush the flowers with olive oil and bake until golden (about 3 minutes). Do keep an eye on them so they don't burn.
Allow the tortilla croustades to cool.
To make the smoked salmon dip, shred the fish, then add sour cream, mayonnaise, lemon juice, fresh dill, sriracha, sea salt, and pepper.
Mix until combined.
Spread cream cheese carefully on each tortilla flower 'petal'.
Sprinkle black sesame seeds along the edges of the flower, or dip the croustades into a small bowl of seeds.
Spoon a small amount of dip into each tortilla.
Top with red caviar and fresh dill.
Serve.
