- In a small non stick pot, stir in 2/3 cup Kikkoman Teriyaki Marinade and Sauce, 2 tablespoons of juice, and sugar until combined, and then bring to a boil over high heat. Reduce to low and simmer until reduced to about half the amount (about 10-15 minutes). Transfer to a small bowl and let cool to room temperature. This can be prepared ahead of time and refrigerated.
- While sauce reduction is cooling, prepare the mascarpone cream. Using a stand mixer fitted with the whisk attachment, whisk the mascarpone cheese, honey, 1 Tablespoon of juice, and salt at medium speed for about 30 seconds or until well mixed.
- Reduce the speed of the mixer to low and slowly pour the heavy cream. Once cream is all added, scrape down the sides of the bowl, and return the mixer to medium speed. Whisk until firm peaks form (about 1 minute). Refrigerate the mascarpone cream. The mascarpone cream can also be prepared ahead of time.
- To grill the peaches, bring a griddle or grill to medium-low heat. In a small bowl, stir in together olive oil and _ tablespoon of Kikkoman Teriyaki Marinade and Sauce just until combined. Brush each peach half with the oil mixture as well as the griddle surface and place peaches on the heated griddle or grill. Grill the peach halves until they are slightly softened and have dark grill marks (5-6 minutes).
- Serve grilled peaches warm or at room temperature, topped with the mascarpone cream and drizzled with the Teriyaki reduction. You can garnish with fresh mint leaves if desired. Piping (instead of simply spooning) the mascarpone mixture is optional although makes it prettier.
