Using a paring knife, split each vanilla bean open lengthwise and scrap out the seeds with the flat edge of the knife. Add the seeds and the split vanilla beans into the milk liquids. Heat the milk and cream over medium heat for 5 to 6 minutes, until the liquids come up to a low simmer; whisk occasionally.
Remove the pan from the heat. Microwave the bowl of gelatin for 15 seconds, until it is liquefied. Whisk the gelatin into the cream, then add the crème fraîche, vanilla bean paste, and salt. Whisk until everything is smooth. Pour the panna cotta into six 1/2-cup serving bowls. Refrigerate them until chilled and set, at least 2 hours. Ingredients. 1 quart heavy cream. 1/2 cup sugar. 1/2 vanilla bean, split lengthwise, seeds scraped. 2 1/4 teaspoons unflavored powdered gelatin. 3 tablespoons water. Mixed berries, for serving. . 23 108 256 417 347 69 16 90
