In a medium sized pot, over medium heat, cook the peaches, brown sugar, vanilla seeds and Baking salt until the peaches are tender but not falling apart.

In a small bowl, whisk together the sugar and starch, then stir the mixture into the peaches and cook for 2 minutes. The juices will look milky when you add the starch and should be clear and thick once the 2 minutes are done. Pour peaches into a bowl and refrigerate to cool. This can be done a day ahead.

In a medium saucepot cook the raspberries and sugar until the juices are as thick as maple syrup. Depnding on the fruit this can take 5 to 10 minutes. Strain through a fine mesh strainer to remove the seeds. Refrigerate the coulis until well chilled. Can be done a day ahead.

Place a two quart or larger container in the freezer to chill before starting your ice cream. This will prevent the ice cream from melting as you add it to the container after it churns.

In a blender, add the heavy cream, half & half, vanilla, sugar, Baking salt and ½ of the chilled peach mixture. Blend for about 30 seconds. Most of the peaches will be pureed into the cream but it doesn’t need to be perfectly smooth.

Freeze the mixture according to your ice cream maker’s instructions.

Place 1/3 of the ice cream in the prepared frozen container. Smooth out the top and then pour about a ¼ cup of the coulis over the top.

Repeat with another layer of the ice cream. The coulis will want to slide around, so you will have to very gently coax the next layer of ice cream into place. Add another layer of coulis.

Spoon on final layer of ice cream and finish with a ¼ cup of coulis. You will have more coulis left over for pouring over the ice cream when you serve it.

Freeze until ready to serve. If you freeze the ice cream for more than 3 hours before serving, remove the ice cream from the freezer about 20 minutes before scooping to temper it (make sure it’s not set too hard). It’s better to be a little melty then to be hard.

Use an ice cream scoop dipped in hot water to serve. Add more coulis and some fresh berries if you are serving in a bowl.

In a large bowl, add 6 cups of ice, plus enough water to cover the ice, and 1 tablespoon Diamond Crystal Salt. Set aside.

Use a sharp paring knife to cut an X in the bottom of the peach skin, try not to cut too deeply into the flesh of the fruit.

Bring a large pot filled with water to a boil. Add the 4 peaches to the boiling water. Let them cook for about 30 seconds, remove and plunge immediately into the ice water.

Use your fingers to peel away the skin, it should fall right off. If it resists, put it back into the boiling water for a few more seconds.
