Grind saffron stigmas in a mortar, add to yogurt, stir and let it brew (1-2 hours).
Heat gelatin with 1 tbsp. l. water over low heat without bringing to a boil. Heat the milk to 90°C (almost boiling). Pour the gelatin into it and stir until the gelatin is completely dissolved.
Mix yogurt, 10 g of finely chopped rose petals and 2 tablespoons of flower honey. Add milk with gelatin to the honey-yogurt mass, stirring constantly. Whisk well until bubbles.
Lubricate the molds with a small amount of vegetable oil, put 2-3 whole rose petals on the bottom, fill with mousse, refrigerate for 6-8 hours.
Remove the mousse from the molds and sprinkle with toasted almond petals. Separately serve flower honey with roses.
