Pour the water into a small saucepan and sprinkle the gelatine evenly overtop. Let sit for 5 minutes until fully absorbed.
Turn the heat onto low and let the water and gelatine mixture gently warm up, stirring until the gelatin is completely dissolved. Do not boil.
Add the strawberries, skyr, milk, honey, lemon juice, vanilla, collagen, and salt to a blender. Blend until completely smooth.
With the blender running on low, slowly pour in the warm gelatine mixture and blend just until incorporated.
For the smoothest, most elegant texture, pour the mixture through a fine mesh sieve (I don't mind the seeds, but it's up to you!).
Divide between ramekins, jars, or glasses and refrigerate for at least 4 hours, preferably overnight, until softly set and jiggly.
Serve on its own, or with fresh strawberries, and / or a dollop or cream. If you want to plate the panna cotta, first de-mold it by running a knife along the edge of the ramekin, submerging about 3/4 of it in recently-boiled water for 20-30 seconds, placing a plate on top then inverting it - the panna cotta should release with a little of the cream melted and saucy. I love it this way! Say thank you and enjoy.
Store any leftovers in the fridge for up to one week.
