Stir in vanilla. Remove from heat.

Sprinkle gelatin over cold water. Let sit 1 minute, then stir until dissolved.

Whisk gelatin into warm cream until smooth.

Divide mixture into four small jars. Cool to room temp, then chill 4 hours.

For compote, heat berries, 2 tbsp sugar, and lemon in a small pan. Simmer 5 minutes until saucy.

Cool compote, spoon over chilled panna cotta, and serve.
