5) coal crushing
煤的破碎
补充资料:松软金沙玉米
材料:
甜玉米罐头一罐、青豆(豌豆)100g、红甜椒一个、咸蛋黄10个、姜片少许、料酒少许
制作方法:
1、罐头甜玉米沥干水份待用。红甜椒切成小粒,在不放油的锅中稍稍炒干水气。
2、咸蛋黄用微波炉叮熟,压成粉状(尽量压细)待用。
3、青豆洗净沥干,均匀的裹上薄薄一层生粉,放入6成热的油锅炸至表面略微发皱。
4、锅中留底油(油要少),放入姜片呛锅后夹出扔掉,咸蛋黄加少许料酒小火炒至翻沙,然后放入玉米粒和青豆翻炒至熟,最后加入甜椒粒再翻炒均匀,即可起锅。因为有了咸蛋黄的缘故,偶就没有放盐了,不过,大家做的时候可以尝尝味道,如果觉得差点咸味,再适量加盐。
