1. Dairy Products
Milk, cream, sour cream, and some soft cheeses can separate or curdle when exposed to prolonged cooking.
Instead of adding them at the beginning, consider stirring them in near the end of cooking when the recipe calls for it.
This can help preserve their creamy texture.
2. Fresh Seafood
Delicate fish and seafood generally don’t need several hours of cooking.
If added too early, they can become dry, rubbery, or fall apart completely.
For recipes that include seafood, adding it toward the end is often a better approach.
3. Fresh Herbs
Fresh herbs can lose much of their bright flavor during a long cooking process.
Heartier herbs such as rosemary and thyme can tolerate longer cooking, but delicate herbs like parsley, cilantro, and basil are usually better added near the end.
That gives the finished dish a fresher aroma and flavor.
