To prepare a Chef Johns strawberry ice cream recipe, first you'll need to gather your ingredients. First, you will need 2 cups chilled whipping cream, 1 cup chilled confectioners' sugar, and 1 teaspoon vanilla extract. You will also need 1/2 cup cold water. Next, add the sugar mixture to the cream mixture and stir until it's completely dissolved. Then, pour the mixture into an 8x8x2 inch pan and freeze it for at least 8 hours. Finally, remove the frozen mixture from the freezer and pour it into serving bowls.
