Seasons - almost a year in Amherst



Since last August, I have been Amherst for almost a full year. These photos were taken during the last months. From summer, to autumn, to winter, to current spring, if I never take these photos, I even don't notice how time flies. If I never take these photos, I even can not remember these changing weathers, and beautiful memories. Anyway, wish the following days of the first year at Amherst, I can have a research harvest. Hope my research result would turn to a paper published... So I can enjoy American summer happily.

about beef titi

1.选 2.腌 3.火侯,三道工序,都会影响炒肉片的嫩老。 


1.牛肉选购是第一关键,挑选牛肉大有文章,
嫩质牛肉适合炒肉片,火锅. 如用于炖,烧.则嚼如木屑.
老质牛肉适合炖,烧. 如用于炒肉片,火锅 .则嚼如皮筋.

牛肉品种繁多,适合炒肉片的嫩质牛肉只占供肉总量25%,价格又贵.不得不多下功夫.中
餐馆炒牛肉片大多选用: 里脊 Tenderloin,Porterhouse,T Bone, 外脊 Rib eye, 米龙
Top Sirloin,($12-5/lb)。

我曾试用过Round(后腿肉$2.49),结果口感嫩老和风味相差甚远。也试用过 Chuck(前腿
肉$1.49/lb)结果难以容忍(齿).牛肉各部位简解见文末附表.

2。腌制吸汁工序是第二关键,腌制吸汁保证肉片成品汁饱嫩滑,至关重要,肉片吸汁越多
,口感越水嫩(餐馆诀窍).
具体做法:牛肉切片时 看清肌肉纹理,横截纤维,下刀切片。按照菜谱把调味料伴入牛肉
片,可酝量多加些盐(50-80%),同时伴入挂浆水淀粉。冰箱冷置约30分钟后加水20-30%,
分批伴入(约20分钟),肉片越咸越能吸水.腌制完毕放冰箱备用.
笔者不赞成放苏打粉Baking Soda破坏风味.可酌情加些嫩肉粉 Meat Tenderizer,其主
要成份(按量)依次是盐,糖,木瓜蛋白酶.

3. 火侯:中火热油,下牛肉片(主料)划散,至变色立即出锅。
洗锅,按菜谱炒制配料(如青椒,青花菜等)炒至九分熟,倒入牛肉片,伴炒入味,数十秒钟
即可出锅装盘。(炒制配料时可少放些盐)
