🔬 Why This Recipe Works (Quick Science)
Ratatouille is all about layering flavors. Slow cooking allows the vegetables to release their natural juices and blend together without turning into mush. The acid from the tomatoes balances the sweetness of the bell peppers and onions, while herbs like thyme and basil pull everything together.
