Turn on the oven to 175°C / 350°F (grill setting).
Cut out the flower tortillas with a flower-shaped 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.
Once cool, spread some cream cheese on each 'petal'.
Sprinkle black sesame seeds onto the flower's edges.
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.
Spoon a small amount of dip into each croustade.
Top with red caviar and fresh dill.
Serve.
