Why This Recipe Works

Blending fresh citrus and mineral salt creates unexpected depth, while Swerve confectioners adds sweetness without spiking blood sugar. Garlic and shallots ground the blend with earthiness, leaving thyme to linger as a subtle finishing note.

I’ve optimized prep flow: whisking foundation ingredients first allows emulsification stability, while reserved olive oil ensures smooth, lump-free consistency—all under 300 calories per serving.

Ingredients

Fresh lemon juice	6 Tbsp	Grate zest first, then juice. Store extra in freezer-safe containers
Minced garlic	2 tsp	Purchase pre-minced for busy nights
Minced shallot	2 tsp	Secured in oil reduces bitterness
Dijon mustard	1 tsp	Opt for white mustard for milder flavor

Step-by-Step Directions

Emulsify with Olive Oil

1. SLOWLY drizzle olive oil into vortex from height of 6 inches

Chef Tips for Perfect Results

• Chill bowl first to thicken dressing faster
• Dry cut herbs reduce by 50% compared to fresh
• Whisk in ½ tsp vinegar at a time to balance acidity
• Use EVOO with strong fruit notes for optimal emulsification

Common Mistakes to Avoid

• Over-mincing garlic: Produces harsh bitterness – slice instead
• Adding zest raw: Heat oil briefly before infusion
