How to Make It
In a large saucepan, combine the whole milk with the goat milk, buttermilk and heavy cream and bring to a boil over high heat. Boil over moderately high heat for 1 minute, then remove from the heat and let stand until curds form and rise to the surface, about 5 minutes.
Line a colander with a double layer of moistened cheesecloth and set it over a large bowl. Using a fine sieve, scoop the mixture into the colander. Drain the ricotta until thick, about 30 minutes. Transfer to a medium bowl. Stir in the 1/4 cup of oil; season with salt.
Spoon the ricotta onto plates. Top with the peaches and season with salt and pepper. Drizzle with olive oil and honey, garnish with mint and shiso and serve.
Fresh goat milk is available at specialty food markets.
