Turn on your oven to 175°C/ 350° F.
Cut the tortilla flowers with the cookie cutter.
Press the flowers into the muffin pan.
Brush the top with olive oil.
Bake for 3-5 minutes until the flowers are golden.
Allow to cool in the pan.
Mix the sour cream, juice of half a lemon, sea salt, pepper, and dill (do chop it if you are using fresh).
Spoon the sour cream mixture into the tortilla flowers.
Halve the avocado and remove the pit.
Gently peel the avocado and slice it thinly.
Individually place the avocado slices into the tortilla base, overlapping and curving them as you go to resemble a rose. Use larger pieces of avocado around the perimeter of the tortilla and the smaller pieces towards the middle.
Twirl the avocado centerpiece around itself and place it in the middle.
Stick two basil leaves to one side.
Squeeze lemon juice over the roses to prevent browning.
Sprinkle with sea salt.
Serve.
