Heat a skillet over medium heat. Pass the peach slices through the sugar and immediately brown in the hot pan.
Turn de peaches with a kitchen clamp and add the butter. When the butter is melted add the orange juice to make a sauce. Reduce 3 minutes more on the fire.
Let cool the peaches at room temperature.
For the yogurt cream:
Mix the natural yogurt, cream, and 2 tablespoons of sugar in a medium bowl and beat with a hand mixer until stiff. Set aside.
For the candied almonds
Place the almonds on a baking sheet and toast in the oven (350F). Let cool.
In a deep saucepan bring to boil the sugar and water for five minutes until a syrupy consistency is formed.
Remove from heat and add the almonds. Stir constantly with a wooden spoon until sugar crystalizes and covers the almonds. They should be white and dry.
Dessert assembly
Place 3 or 4 peach slices per glass/cup. Add a few tablespoons of yogurt cream and end up with a few strings of peach sauce and candied almonds or sliced toasted almonds.
Notes
You can prepare the yogurt cream, peaches, and almonds in advance and assemble the trifle when ready to serve. Keep the cream and peaches covered in the fridge.
Keep leftovers covered in plastic wrap in the fridge for up to 3 days. It's better to separate the peaches and almonds from the cream.
