In a medium saucepan, combine the 960 ml heavy cream, 100 g sugarand 1 tsp. vanilla extract.
Heat over medium heat until just simmering. Remove from heat, cover, and allow to steep for 15 minutes.
While the cream is steeping, in a small mixing bowl, sprinkle the 7 g unflavored powdered gelatin over the 45 ml water. Let it sit for about 5 minutes until the gelatin is evenly moistened.
After the cream has steeped, uncover and return it to moderate heat, bringing it just back to a simmer.
Remove from heat and stir in the bloomed gelatin until fully dissolved.
The Cooling
Carefully pour the panna cotta mixture into your ramekins or coupe glasses. Allow them to cool to room temperature.Denis Tip: If you do not have any of those glasses, any kind of glass works too.
Once cooled, cover with plastic wrap and refrigerate until set but still slightly jiggly, at least 3 hours. The panna cotta will keep in the refrigerator for up to 3 days.
