Fix Your Broken Homemade Mayo

The Science Behind It:

Homemade mayonnaise is an emulsion, which means it's a mixture of two liquids that normally don't mix well, oil and water. The emulsifying agent, usually the lecithin found in egg yolks, helps these two substances blend into a smooth and stable mixture. When mayonnaise 'breaks' or separates, it means the emulsion has been disrupted, usually due to factors like overmixing, too rapid oil addition, or temperature differences.

Adding cold water can sometimes help re-emulsify the mixture by providing a shock that helps the dispersed oil droplets come back together. If this method fails, reintroducing a fresh egg yolk offers a new emulsifier to stabilize the mixture and gradually adding the separated mayonnaise can help restore it.

How to Do It:

1. Whisk in Cold Water - Add a tablespoon of cold water to the separated mayonnaise and whisk vigorously. The cold water can help re-establish the emulsion by reducing the size of the oil droplets and distributing them evenly.

2. Restart With a New Yolk - If the water trick doesn't work, place a fresh egg yolk in a clean bowl. This yolk serves as a new base for the emulsion.

3. Gradually Add Broken Mayo - Slowly whisk the broken mayonnaise into the new yolk, a little bit at a time. This gradual process allows the fresh yolk to absorb and stabilize the oil, effectively rebuilding the mayonnaise.

4. Adjust Consistency and Flavor - Once the mayonnaise is back to its smooth state, you can adjust its thickness by adding more oil or water, and season to your taste. Let your imagination be your recipe.

The Big Fix:

Creating the Emulsion - The key to fixing separated mayonnaise is to re-establish the emulsion. Use a whisk or even an electric mixer set on a low speed to blend the ingredients effectively. When whisking by hand, make sure to whisk in one direction to help the oil droplets merge uniformly with the water content from the egg yolk and vinegar or lemon juice.

Incorporation - If using water, add it one teaspoon at a time, whisking continuously until you see the mayonnaise start to thicken and smooth out. If the mayonnaise remains broken, use the egg yolk method: transfer a fresh egg yolk to a bowl and very slowly whisk the separated mayonnaise into it. The lecithin in the fresh yolk acts as a more potent emulsifier to help bind the oil and liquid components.

Room Temperature - To prevent future emulsion issues, start with all ingredients at room temperature. Cold ingredients can shock the emulsion, making it more likely to break. This is especially important for the oil and egg yolk. If your ingredients were stored in the refrigerator, take them out about 30 minutes before you plan to make your mayonnaise. This slight adjustment in preparation can make a big difference in maintaining the stability of your mayonnaise.

When initially making mayonnaise or fixing a broken one with a new yolk, add oil very slowly. A thin stream or even droplets at the beginning helps establish a strong and stable emulsion. Use an oil that is neutral in flavor and known for making good mayonnaise, such as canola or light olive oil. Oils with strong flavors or varying consistencies can affect the stability and taste of your mayonnaise.

Once your mayonnaise is stable and creamy again, give it a taste and adjust the seasoning if you like. Sometimes a little extra pinch of salt or a few drops of lemon juice can brighten the flavor after the rescue process.
