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...

300 g tomato 10 g sugar
5 g oil 2 1/2 g 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
