使用JAVA对下面的复杂文本进行解析，这是一个菜谱的txt文本文件，下面只列出两道菜谱，其余格式都相同.只要能分别解析出Name，Categories，和下面的配料，存入一个对象中即可。请给出解析步骤的详细代码

大侠们拜托了，之后必定追加最高分.

下面是菜谱的文本格式

Name： Yu xiang rou si
Categories: Pork, Chinese

  500 g Pork            10 g sugar
   10 g chilly       1 1/2 g salt   
   15 g oil

In large bowl, blend oil and sugars on low until well mixed. Add chilly.
Beat in salt...

Name： xi hong shi chao ji dan
Categories: tomato, Chinese

  300 g tomato          10 g sugar
    5 g oil          2 1/2 g salt   
   
Chop tomatoes, blend oil and sugars on low until well mixed.
add some  salt...

配料部分是不确定的, 比如
  2 1/2 c  Brown sugar                         2 ts Cloves
      2 c  Sour milk                           2 ts Nutmeg
      4 c  Flour                               3 ea Eggs, lg
    3/4 c  Butter                             15 oz Raisins
      2 c  Jam                                 1 c  Nutmeats
      2 ts Baking soda                         1 x  Figs and dates as desired
这个也应该需要解析至少存在一个数组或者list里
