A panna cotta is similar to pudding though there is an option of chilling the mixture in chilled ramekins overnight for a firmer texture. It's one of the easiest desserts to make in my opinion. Sorry I can't post an official link to the recipe but basically...
Step 1: 2.75-3 tsp of unflavored gelatin sprinkled onto .25 cups of milk
Step 2: Just bring to a boil- 3 cups heavy cream with .75 cups of milk
Step 3: Combine hot and cold mixtures along with 2 tsp of vanilla and a pinch of salt
Step 4: Pour into desired container and chill for 3-4 hours.
