Which Herbs Work and When
My herb bed does most of the work from May through October, but the skill was never growing them, it's knowing when to actually put them in the pot. Rosemary can simmer in a stew for an hour and come out fine. Basil dropped in five minutes too early turns dark and bitter. Here's the difference, herb by herb, plus what to do when all you've got is the dried jar.
Fresh to dried, herb by herb
The general rule is 1 tablespoon fresh equals 1 teaspoon dried, roughly 3:1, because drying concentrates the flavor. But that rule bends depending on the herb, and knowing where it bends is what actually saves a recipe.

When to add them, hardy versus tender
Woody herbs can take the heat. Soft, leafy herbs cannot. Add them at the wrong end of the cooking process and you either get no flavor at all, or a bitter, blackened mess on top of your dinner.
Rosemary, thyme, sage and bay leaf are sturdy enough to simmer for an hour in a stew or braise without breaking down. Add them with the onions and stock.
Oregano and marjoram hold up reasonably well but start to fade with too much time. Ten to fifteen minutes before the dish is done is the sweet spot.
Basil, cilantro, parsley, dill, chives and mint bruise and darken fast. Stir them in right before serving, or use them as the garnish.
What actually pairs with what
Same information, organized by what's in the pan instead of which herb you're holding.
Five herb mistakes worth fixing
Basil and cilantro wilt, darken and turn bitter over sustained heat.
Dried is more concentrated. Use about a third of what the recipe calls for in fresh.
Cold bruises it black. Treat it like cut flowers instead, a glass of water on the counter.
Rubbing dried herbs between your palms before they go in releases the oils that carry the flavor.
Fresh herbs go limp fast. I only buy what a specific recipe needs, plus a little for a garnish.
