Can I make this without an immersion blender?
Yes. Use a food processor or regular blender to puree the sun-dried tomatoes and garlic first, then whisk them into store-bought mayonnaise or hand-emulsify with the egg yolk using a whisk and bowl.
Why won't my mayonnaise emulsify?
Ensure your egg yolk and all ingredients are at room temperature, add the oil very slowly at first (especially the first tablespoon), and whisk or blend continuously to prevent breaking.
How long does sun-dried tomato mayonnaise keep?
Store in an airtight container in the refrigerator for up to 5 days. Because it contains raw egg yolk, do not leave it at room temperature for more than 2 hours.
Can I use oil-packed sun-dried tomatoes?
Yes—use the oil from the jar as part of your emulsion. Drain dry-packed sun-dried tomatoes and rehydrate them in warm water for 10 minutes before blending.
Is this safe to eat with raw egg yolk?
Use pasteurized eggs or pasteurized egg yolks to reduce food safety risk, especially for pregnant women, young children, or immunocompromised individuals.
