Preheat an oven to 180°c/160°c fan (356°f/320°f).
Place the flaked almonds onto a baking tray then toast in the preheated oven for 4-6 minutes until golden brown. Give the tray a shake halfway through so that the nuts toast evenly.
Whilst your almonds are toasting, place the cream, milk & vanilla into a medium saucepan then set over a low heat & warm until steaming hot.
Next, stir the toasted nuts into the warm cream then take the pan off the heat & cover it with a lid. Set to one side & leave to infuse for 1 hour.I'd recommend roasting the peaches whilst the cream is infusing, as they're also cooked at 180°c/356°f. Once the cream has been infused, set the pan back over a low heat & warm until steaming hot again. Pass the cream into a jug through a sieve then stir in the almond extract. Set this to one side for now.
Add the sheets of gelatine into a bowl of cold water & leave to soak.Adding the sheets of gelatine into the water one at a time helps them soak better. Next, add the honey into a medium saucepan then set over a medium-high heat. Cook for 3-4 minutes, until it turns a deep golden brown (like caramel). Agitate the pan frequently so that the honey cooks evenly.
As soon at the honey is cooked, slowly pour in the almond cream whilst stirring. Once incorporated, take the pan off the heat & stir in a pinch of sea salt.Do this step carefully! The honey will bubble as you add in the cream. Squeeze as much water as you can from the soaked gelatine then add to the cream & stir until dissolved. Pass through a sieve into a bowl (metal is best).
Next, fill a larger, separate bowl up with ice & water then place the bowl containing the cream into the bowl of water.
Stir the panna cotta mix regularly until it has cooled down & has started to thicken. This will take around 20 minutes.Allowing the panna cotta to cool like this holds the vanilla seeds in suspension, preventing them from sinking. Transfer the panna cotta mix to a jug then pour into the moulds. Place in the fridge & leave to set. This will take a minimum of 4 hours.
