Alternatively, if you are intimidated by a custard-base ice cream, you could just use 2 whole eggs instead of 5 egg yolks and skip the process of heating the cream, milk and sugar then tempering the eggs. Just follow the steps of the recipe with the peaches, sugar, and lemon juice, then to make the ice cream base, just whisk the 2 whole eggs really well in a large bowl before slowly adding the sugar while whisking. Stir in the cream, milk, vanilla and peach juices, then continue with the recipe as written to churn and freeze.
