Hint 1: There are 6 themed entries, which are easy to spot—they're all marked with parenthetical numbers. The longest across entry gives you a huge nudge as to what to do with them.
Hint 2: So what do the numbers in parentheses mean? They usually denote either word length or letter order. Note that there are 2 numbers per themed entry, which means that each entails 2 steps.
Hint 3: Notice how odd the themed grid answers are? That's always a big hint.…
Hint 4: .…They're all anagrams. The puzzle's theme should be obvious by now—it's food. They're all food anagrams.
Hint 5: Once you've solved the anagrams, think about what links them as a group, then use each anagram as a clue to derive another answer for each entry. The first parenthetical number indicates the word length specific to each clue (you can figure this out via process of elimination).
Hint 6: You've found the word each anagram hints at. Now what? Well, there's a second number, which is either the letter order for the meta answer, or tells you that you're looking for a second word. The only way to find out is to test it.
Hint 7: So you're looking for a second word. What could it be? Again, use that first word as a clue to obtaining the second final word. The second parenthetical number tells you the number of letters you're looking for specific to each clue.
Hint 8: Look back at the other clues if you're stuck.
Hint 8: The meta answer is also an anagram, albeit a very easy one.
