Yes, you can make vinaigrette in a blender or food processor. Using a blender or food processor generally results in a more stable and emulsified vinaigrette compared to hand mixing.
Making vinaigrette in a blender or food processor leverages the machine's power to create a finer emulsion between the oil and vinegar. Here's a step-by-step guide:
Gather your ingredients: You'll need your choice of vinegar (balsamic, red wine, white wine, etc.), oil (olive oil, avocado oil, etc.), and any desired flavorings (Dijon mustard, honey, herbs, garlic, shallots, salt, pepper).
Combine ingredients (except oil): Place all ingredients except the oil into the blender or food processor.
Blend/Process: Start the blender or food processor on a low speed.
Slowly drizzle in the oil: While the machine is running, slowly and steadily drizzle the oil into the mixture. This is crucial for creating a stable emulsion. The slow addition of oil allows it to break down into tiny droplets and fully incorporate with the vinegar and other ingredients.
Continue blending/processing: Continue until the vinaigrette is smooth, creamy, and emulsified. This usually takes about 30-60 seconds.
Taste and adjust: Taste the vinaigrette and adjust the seasoning as needed. You may want to add more salt, pepper, vinegar, or oil to achieve your desired flavor profile.
Store: Store the vinaigrette in an airtight container in the refrigerator. The emulsion may break down over time, so whisk it again before serving.
The high-speed blending or processing breaks the oil into smaller droplets, which are then suspended in the vinegar. This creates a more stable emulsion that is less likely to separate quickly compared to hand-mixed vinaigrettes. Hand mixing relies on manual whisking, which is less efficient at creating a fine emulsion.
For a richer, creamier vinaigrette, add a small amount of mayonnaise or Greek yogurt to the blender along with the other ingredients. This will further stabilize the emulsion and add a pleasant texture.
