In a small bowl, sprinkle gelatin over cold water and let bloom for 5 minutes.
In a saucepan, combine heavy cream, milk, and salt. Warm over medium heat until just simmering. Do not boil.
Remove from heat, stir in the bloomed gelatin until fully dissolved.
Whisk in Manuka honey and vanilla extract until smooth.
Set the bowl in an ice bath and stir occasionally until it cools to room temp. Taste it here and adjust the sugar, because once it is poured nothing can be changed.
Pour mixture into ramekins or serving glasses.
Refrigerate at least 4 hours or until set.
Serve chilled, optionally drizzled with more Manuka honey or fresh berries.
Notes
Storage: Keeps covered in the fridge for up to 4 days, the texture holds up nicely. Cover ramekins with plastic wrap once fully set so they don't pick up any fridge odors.
