Finding a NSString in an Array in a Master Array

I have a string called alpha.

alpha= @"pie"

I have 3 arrays that were added into a master array called "ALL WORDS"

array 1 = [nsarray alloc]initwithobjects @"cake", @"donut"];
array 2 = [nsarray alloc]initwithobjects @"cream", @"pie"];
array 3 = [nsarray alloc]initwithobjects @"rice", @"flour"];
 
 
    allwords = [NSMutableArray array];
    [allwords addObjectsFromArray:array1];
    [allwords addObjectsFromArray:array2];
    [allwords addObjectsFromArray:array3];
So now I am doing a for loop like this
 for (int i = 0; i < [allWords count]; i++)
 {
        NSString *takestring =[allWords objectAtIndex:i];
        if ( [takestring is equal to alpha]) {
           //tell which array alpha or takestring came from????            
        }        
 }

My question is, how can I determine which array the pie came from. in the app people might have new words that I might not know, but i want to be able to detect where that string what array is it from?

Anybody knows how I can do this??

@interface aViewController ()
@property (nonatomic, strong) NSMutableArray *allwords;
@end

@implementation aViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.

    NSArray *array1 = [[NSArray alloc] initWithObjects:@"cake",@"donut", nil];
    NSArray *array2 = [[NSArray alloc] initWithObjects:@"cream", @"pie", nil];
    NSArray *array3 = [[NSArray alloc] initWithObjects:@"rice", @"flour", nil];
    self.allwords = [[NSMutableArray alloc] initWithObjects:array1, array2,

array3, nil];

[self findMyArray:self.allwords];
}

- (void) findMyArray:(id)array {
if ([array isKindOfClass:[NSArray class]] ||

[array isKindOfClass:[NSMutableArray class]]) {

       for (NSArray *temp in array) {
           for (NSString *str in temp) {
               if ([str isEqualToString:@"pie"]) {

// define @"pie" as per your requirement
                  NSLog(@"THE ARRAY WHICH CONTAIN PIE IS %@", temp);
              }
          }
      }
}
}
@end
