Zest and juice the lemon first so you capture the bright oils and fresh juice; the aroma will lift your spirits the moment you begin.

In a small bowl or mason jar, combine the lemon juice, lemon zest (if using), minced garlic, Dijon mustard, honey, salt, and pepper. Whisk briefly until combined.

Slowly drizzle in the olive oil while whisking vigorously (or add the oil to the jar and screw on the lid). Shake vigorously for 20 to 30 seconds to emulsify.

Taste and adjust: add more salt, a touch more honey if too tart, or another splash of lemon if you want extra zing.

Stir in any fresh herbs if you like — chopped parsley gives a clean lift, basil adds sweetness, tarragon lends a gentle anise note.

Use immediately or chill for 10–15 minutes to let flavors marry. Before serving, give it a good shake or whisk.
