Critical Thyme Questions Answered
What's the exact dried-to-fresh thyme conversion?
Dried thyme is three times more concentrated. Use 1 teaspoon dried for every 1 tablespoon fresh. Measure dried thyme with measuring spoons, not by volume estimation.
Why does my dried thyme taste bitter?
Bitterness indicates age or improper storage. Replace if older than 9 months or exposed to light/moisture. Test potency by rubbing leaves—if aroma is weak, discard immediately.
Which thyme variety works best for cocktails?
Lemon thyme complements gin-based drinks perfectly. Muddle 3-4 leaves with citrus for subtle herbal notes that enhance without overwhelming sweetness.
Does cooking destroy thyme's flavor?
Thymol remains stable during prolonged heat, but delicate terpenes degrade after 2 hours. For optimal flavor, add fresh thyme in last 30 minutes of cooking.
Can I grow thyme indoors year-round?
Yes—with 6+ hours of direct sunlight or grow lights. Use gritty soil mix and water only when top inch of soil dries. Harvest by snipping top growth to encourage bushiness.
Why do recipes specify "remove thyme stems"?
Woody stems contain bitter tannins and create unpleasant texture. Only tender leafy portions provide balanced flavor—stripping takes 20 seconds but elevates results significantly.
