Most ice cream contains multiple allergens (dairy, eggs, soy, corn...) The peach ice I describe here consists entirely of fresh peaches, lemon juice and sugar, yet is smooth and luscious. Just be sure to start with totally ripe peaches.
The acidity of the lemon juice wakes up the flavor of the peaches; if you're allergic to citrus, experiment with other sour fruit juices.
4 large, fresh, thoroughly ripe peaches (See Produce in the Glossary)
fresh squeezed juice of 1/2 lemon (See Juice in the Glossary)
1/2 c. sugar (or to taste) See Sugar in the Glossary
First place the container for the peach ice in your freezer. (A warm container could melt some of the ice when you first scoop it into the container.)
Peel and seed the peaches. Puree the peaches and lemon juice in a blender. Add the sugar and blend it in too.
Follow the instructions for your ice cream maker.
