Easy Homemade Olive Oil Mayonnaise
To make without an immersion blender: Combine eggs, white wine vinegar, lemon juice, dry mustard, and salt in a blender. Place the lid on the blender without the center insert. Combine olive oil and canola oil together in a paper cup. Blend on medium speed. Puncture a small (using a toothpick or similar sized item) in the bottom of the paper cup and quickly cover the hole with your finger. Place cup over the opening in the lid of the blender and continue blending until all of the oil has dripped into the blender and the mixture has emulsified. This will take considerably longer than with an immersion blender, about 10 to 15 minutes.
