Take 3 biscuits per person, and grind them into a powder using a mixer or simply bashing them around a bit! Spoon the powder into the bottom of tall transparent glasses.
Cut the peaches into small chunks, two halves per person. Dollop onto the biscuit powder in the glasses.
Fill the rest of the glasses with the fromage frais.
Place in the fridge until dessert-time.
Before serving, add a topping such as icing sugar and a frozen mint leaf or cinnamon and a drizzle of honey.
