Preheat your Grill to medium-high heat (about 400°F). Clean the grates well and oil them lightly using a folded paper towel dipped in Oil, held with Tongs — this prevents the 4 peaches, 去核、对半切开、成熟 (成熟但坚实) from sticking.

Halve the 4 peaches, 去核、对半切开、成熟 (成熟但坚实) along their natural seam and twist to separate. Remove the pit with a spoon or your fingers. Leave the skin on — it holds the 4 peaches, 去核、对半切开、成熟 (成熟但坚实) together on the Grill.

In a small Mixing Bowl, stir together the melted 2 tbsp 无盐黄油 融化, 2 tbsp 红糖 压实, 1 tsp 香草精, ½ tsp 肉桂 (if using), 2 tbsp 无盐黄油 融化, and 1 tsp 新鲜柠檬汁 (if using) until combined.

Brush the cut side of each 4 peaches, 去核、对半切开、成熟 (成熟但坚实) half generously with the 2 tbsp 无盐黄油 融化-2 tbsp 红糖 压实 mixture.

Place the 4 peaches, 去核、对半切开、成熟 (成熟但坚实) cut-side down on the hot Grill. Do not move them — let them cook undisturbed for 4 minutes until deep golden grill marks form and the 2 tbsp 红糖 压实 has caramelized.

Flip the 4 peaches, 去核、对半切开、成熟 (成熟但坚实) skin-side down. Brush the caramelized cut side with any remaining 2 tbsp 无盐黄油 融化-2 tbsp 红糖 压实 mixture. Grill for another 3–4 minutes until the 4 peaches, 去核、对半切开、成熟 (成熟但坚实) are tender when pierced with a Knife but still holding their shape.

Remove from the Grill. Serve warm with a scoop of 4 scoop vanilla ice cream (optional) (每份1勺), a drizzle of 2 tbsp 蜂蜜 用于淋酱, and fresh 2 tbsp 新鲜薄荷叶 用于装饰 if desired.
