Can I use anchovies instead of sardines?
Yes. One anchovy fillet is a direct swap for one sardine fillet and will deliver similar umami, though anchovies are stronger—start with half and adjust to taste.
Is it safe to use raw egg yolk?
Traditional Caesar uses raw egg. Use pasteurized eggs if concerned about food safety, or substitute ¼ cup Greek yogurt for a cooked-egg alternative.
How long does homemade Caesar dressing keep?
Store in an airtight jar in the refrigerator for up to 3 days. The emulsion may separate slightly; whisk or shake before use.
Can I make this without a blender?
Yes. Mash the sardine and garlic into a paste with a fork, whisk in mustard and Worcestershire, then slowly drizzle oil while whisking constantly to emulsify.
How do I thin a dressing that's too thick?
Whisk in water or extra lemon juice, one teaspoon at a time, until you reach the desired consistency.
