Preparation

• In a small saucepan, melt the butter over low heat. Remove from the heat, and add the maple syrup, vanilla, and cardamom (start with 1/8 tsp., taste, and add a bit more if you like). Add a big pinch of salt, and stir to combine.
• Heat a medium (350°F to 375°F) charcoal or gas-grill fire. When the grill is hot (about 10 minutes), scrape the grill grate with a grill brush.
• Put the peaches on a tray or baking sheet, and brush the cut sides with the oil. Arrange the peaches cut side down on the grill, and cook until grill marks form, about 4 minutes. (Try not to move the fruit for the first 3 minutes.) Rotate the peaches 90 degrees to make crosshatch grill marks, if you like, and continue cooking, 3 to 4 minutes.
• Carefully remove the peaches from the grill using tongs and a spatula. (They will be soft and very warm—they do not need to be grilled on the skin side.)
• 将冰淇淋分成6至8个浅碗。在每个碗中加一个桃子一半。如有必要，在低火中轻轻地将枫木黄油重新加热。将黄油倒在每个碗中的水果上。撒上结晶的生姜，如果使用。
